I was washing my car on Sunday and when I went to dry inside my doors and I noticed a large puddle at the kick panel on the passenger side of the car. I dont use a preasure washer and I never spray my car hard. Im wondering if this has happened to anyone or if anyone has heard of this happenening?

Just a thought...is your automatic window still going up and down. There is a switch on the door that turns it off in either position I believe. Just a guess.

[mustang fanatic]

Ill check that out but it almost seems like it came from the door.

[Coltdog]

If the door isn't completely shut, the window will stay about a 1/4" down to prevent a vacuum so that the doors shut more easily. It's a pretty cool feature that you may already know about, but thought I'd throw it out anyway. Once the door is shut, you can actually see it move all the way up.

If your window is not going completely up, it's possible that the short drop glass function needs resetting. Sometimes this feature or the auto up/down function can get lost if your battery has gone dead. You can find where to reset this in your owners manual in the power windows section.
Make sure you do this with the door fully closed.
To recalibrate the window hold the switch in the up position and raise the window until it stops, and then hold the switch for another 2 seconds.
If the glass is not dropping when you open the door, lower the window all the way until it stops, and then hold the switch down another 2 seconds. Immediately after you let go of the switch, raise the window until it stops and then hold it up for two seconds. Remember, do this with the doors closed!

Did this ever get resolved?

I'm having the same issue now. Read a TWENTY page thread about this issue on mustangforums.com My issue started once I replaced my cabin filter, so I think it has something to do with the cowl seals.

(Yes, I know this post is over a year old)

[05mustang_TT_charged]

Damn this post is over a year old!!!!!


Reset the Window up and down stops....Unless your cowl is leaking like you said...and why did you replace the cabin filter?

Car's going to the dealer for the first time since I bought it to have it fixed.

[tribaltek]

I replaced the cabin filter because... well... I never had done it in a car before and I figured why not. It was DAMN dirty too. But apparently I shouldn't have done it.

I really don't think its the window. That seals tight... no issues there.

[tribaltek]

Good luck Redfire. From all the posts I saw at Mustangforums.com, its going to take you at least 3 trips to the dealer to get it fixed right (if at all). I think some people were going six and seven times!!!

Too bad my car is out of warranty.

[tribaltek]

BTW - After a good rain, I get about TWO PINTS of water that comes into the car. I carry a dry towel around with me all the time now

[06RedfireGT]

That sucks man. I would get it taken care of ASAP because all the water getting on the electrical shit under there will really screw shit up.

Mine only leaks when I got through car washes.

[tribaltek]

My leak is getting progressively worse. I know I need to take some serious action this weekend!

I already went thru the TSB and didn't see anything out of the ordinary, but I think I'm going to have to seal up all of those like 1" long pads in the cowl.

[tribaltek]

Also, here are some of the highlights of what I copied from my 20-page read at Mustangforums... And yes, its a lot!



I think I found my problem as others have found the same. I removed the cowl panel on passenger side & there are about 4 recessed plastic pieces that the cowl panel latches into. The cheap gasket on one looked out of place so I pulled one out & the entire area inside was full of water. Those clips don't hold enough tension on the gasket to make a seal. There are also 4 on the driver's side so that's 8 places for water to seep in. Now the water works its way around to the side & drops down onto the dreader junction box. I removed the wipers & other cowl cover & threw out all 8 of those gaskets & reinstalled the clips with some good sealer I have that is for camper seams & such. I am convinced that is the problem as I have heard others describe the water sloshing back & forth when they drive. The problem may have been worsened cause some leaves were blocking the little hole in the cowl panel causing it to fill up & run backwards. Next time you have the leak pop one of those out & look inside. Others have mentioned sealing the seam at the A pillar but I think they are sealing the water in & not solving the problem.
I wanted to add that when this happened my car was not driven, it was parked in the rain. People that have issues with driving in rain may or may not have this problem. I used a product called Permanent sealer by a company called Ruscoe, comes in clear & white I used clear.


They noticed that the firewall-rocker panel seam, and cowl seals came up a lot. They concentrated on those areas, and found that they could get it to leak in those spots. Especially if they rode it on the road after it rained. They sealed the seam, and replaced the cowl with the newer part revision.

Water leaking from hole for main wiring harness above junction box pass side found where it was leaking from by taking out carpet and taking off right front fender. upon further investigation found water leaking from cowel pin seat had to install new right front cowel pin slots ced seats with clear silicone. reinstalled cowel and water tested again leak had stopped. after water test test drove vehicle and found another area where water was leaking from. found a lot of water running between door and rocker panel and was not draining out. had to order door weather stripping, window weather stripping new pass side cowel and cowel pins, hood padding,weather strip for pass mirror new door panel moisture pad and retainers for pass and driver door installed all new parts and water tested agin no leaks and also road tested. found no leaks after road test. reinstalled all panels carpet and seats. vehicle would only leak if vehicle was moving and when applying brakes. pulled pass door panel off and ck how water was running in behind door panel and to see what else was happening.


Here is a pic of the passenger side firewall area, the black
boot is where water drains down from the windsheild wiper
hole(s) in the cowl. The hole shown in the pic is some crazy
shiz....not sure why Ford would allow water to drain into
that area of the body.....



When you open your hood, follow the draining from the windshield and into the cowl. The water is transported down through the marked rubber boots in hammeron's picture. (the yellow) The same design is on both sides, so I don't really see why water would only leak into the passenger side. I took my own pictures by holding my camera phone down into and between the chassis and the engine. However, once you understand where they are, they are easily seen from head height. On my 4.0 V6, it is actually easier to see it on the drivers side. Not sure how that would be on your GT, wingman.
I went to Loew today to get some plastic screws and rubber fittings that I will try to put in there tomorrow. Will post pictures and details about how that went. If not successful, I will use some automotive screws and perhaps some silicone to glue them there. I do have a question on the heat in that area, I'm not sure on how much heat that area is exposed to. Any thoughts on that?
Are we also 100% sure that this is where the water enters? I am not sure I am willing to "tare apart" the interior to find out where that hole leads on the other side. I'd love to hear from someone that actually tried to stick a wire or something through that hole to see if it really comes into the interior/cabin(?).


Topic: Interior water leak (ksmach1 -- 20th December 2006 - 06:26 PM) ............................................
I'm not sure were to post this so I'll start here. I own a 2007 GT500 and only had it for three weeks now. Just this past Sunday, I was washing the car and found water on the passenger side floor. Further investigation, I found that behind the kick panel was also wet. Beware that their is some kind of electrical module that is located behind the kick panel. I took the car back to the dealer and at first they could not duplicate the leak. During a few hours of testing, they moved the car to were the car was sitting at a different angle and than the water began run onto both passenger and driver side floors. Here is my take, the plastic panel that sits over the firewall that covers the windshield wiper linkage is the problem. This panel is attached to the firewall by pins that slide into insert cups installed in the fire wall. The insert cups have some sort of seal but I'm thinking that the seal is not able to hold up to any kind of water build up. Also, it just so happens that one of these inserts is located above the passenger and drivers side kick panels. <_< So what is the dealer doing, so far they reported their findings to Ford tech support and while their waiting on a response, they pulled my carpets up to dry everything out. If I am right about these insert seals not doing the job, this problem may not just be a GT500 thing. At this point I welcome any insight, suggestions, or if you had this same problem with your 05 to 07 mustang. As I get more info from the dealer, I'll post their findings and Fords master plan to make this right. Outside of this problem, the GT500 is an AWESOME PONY!!!


1. a wire grommet in the firewall.
2. a seal along the cowl.
3. a opening in the A-pillar behind the SJB.
4. a floorboard seam.

Well I think I fixed my leak. The water was coming in from the grommet in the firewall above the kickout panel. It wasn't seated properly around the opening. After a few minutes of pushing it finally popped in and seemed to make a good seal. We had some rain on Christmas day so I checked this morning and thankfully found no water. It didn't rain real hard, but it was a steady rain all day. I would suggest that everyone check to see if this would fix yours. I was able to reach under the dash and get my hand on it. If you look under there and see the orange wire for the antenna running from front to back it is about 3 or 4 inches above. Just look (feel) directly above the mid point of the orange wire. I hope that makes sense. It worked for me so far so I hope it does for someone else. I was lucky enough to reach up there when it was wet after a rain shower so I knew exactly where the water was coming in.


Im a tech here in maine at a ford dealership and my 06 mustang has had the same problem. i have a nice benefit of being able to get paid to work on my car. my leak happened about 8 months ago and it was coming in right above the gem module or the smart box as you guys are calling it. The body plug with the wiring harness running through it above the gem module was popped right out of its hole allowing water to come in through that hole. i put the plug back in and taped over it so it could not pop back out. my car has never leaked since so i am pretty sure this is the fix for all of your problems. also make sure that the dealership replaces your carpet cause you dont want that getting all mildewy. well i hope this information is useful for all of you.
This is a very easy fix that anyone should be able to perform sorry i cant post any pics due to not having a camera but i will give a step by step way to do it. first open up the passenger side door and take the sill plate that says mustung on it pull that upwards there are just clips holding it on and it will pop right out. then once you take that out you have to remove the kick panel which is to the right of where the sill plate was near the floor. kinda of pull outwards and back on the kick plate and that will come out because that is just clipped in also. once you have those two items removed lay on the passenger side floor and u will see the fuse box. take a flashlight and look above the fuse box and you will see a black body plug with a whole in it with a wiring harness running through it. i used electrical tape and just taped the plug in and covered up around the wiring harness so the whole was completely covered. then reverse procedure and and everything should be ok. but if you are having any electrical problems i.e tailights staying on or anything else take it to the dealer and get the gem module replaced. becuase if the lights are staying on this means water has got into the gem module and has started to short things out inside of it.well i hope this helps and sorry about not being able to post picture
Edit. this is all done from inside the car no removal of inner fender well


clearym: To make a long story short, I had the notorious passenger side leak, brought it in to the dealer, they farmed out the leak repair to a company called Williams in Langhorne, PA. I'm happy with the way they're handling it since I've been talking directly with Williams. The dealer gave me a free rental (I've had it 3 days now).
Williams says its a body seem at the junction of the pillar, dask, windshield & passenger door. They said they patched it with silicone first and then undercoating spray. They're waiting for is to dry and then they're going to do another water test.


The TSB has the tech looking in no less than 10 places. The water that is entering the cabin is doing so from the cowl. The cowl captures all the water coming off the windshield. It will pool inside the cowl like a sink if the water is entering faster than it can drain. The problem is that the cowl is full of holes (10 grommets for attaching the cowl and a large hole for the filter). If installed correctly all the grommets and the filter gasket and other seal will hold the accumulated water. But anyone one of those grommets or filter gasket or other seals could leak if not installed correctly and that is why so many people are getting leaks from different places. When a certain grommet is leaking, the water will drip onto a cross-beam that runs from the left to the right side of the dash in an arch. Water follows the arch of the beam to the passenger side A-pillar and leaks down on top of the SJB. Some grommets will leak down the firewall. If it's the gasket for the filter then in leaks into the plenum and out the drain hose.

Ok, just wanted to share my "leak" problem. I just got my 05 coupe not too long ago and we had monsoon rains a few days ago. The car sat level in my drive and I didn't drive it during the rain. I went out and checked the floors and they where dry. I thought I was good, but as soon as I started driving water was pooring out from under the dash. About 2 pints came out and I started looking around and it looked like it was coming from the HVAC box. I went under the hood and found the drain and stuck my finger up into it and it was clogged with leaves. I started digging the crap out and about 2 quarts of water came pooring out. I went out driving again and had no waterfalls.
We'll see what happens when we get the next monsoon....
BTW the drain is the rubber flap on the firewall on the passenget side between the engine and battery down near the frame. There is a picture of it in this thread on the yellow car.


Found & fixed my leak last weekend. Only had water get in 2 times in past year & half. Ended up being a poorly installed grommet inside the pass side fenderwell. The plastic inner fenderwell is easy to remove, it's in 2 pieces.
All the water that drains down the windshield & wiper area runs down that grommet. Sealed up the entire area around the grommet.
Took me about an hour,including jacking up, taking wheel off, etc.
Here was my issue,pics;
