I Need Serious Help With Brake Lights And Turn Signals Asap

jarena81 · October 28th, 2009, 11:14 PM

Ok Here Is The Deal I Got A 2002 Mustang Gt, It Had Sequential Tail Lights In It! The Wire Frayed Open And Grounded To The Metal In The Trunk, And Now The Brake Lights Dont Work And Turn Signals Or Hazards! So I Took It To Mustang Magic And They Replaced The Multifunction Switch, Flasher Relay, And Checked All The Fuses! Im Being Told The Only Thing That It Could Be Is The Brake Light Switch......... But That Doesnt Explain The Turn Signals Or Hazards!!!

Does Anybody Know What Is Going On Here?

Moving this to electronics...Hopefully Primo will jump in. I'm too tired

Had the same problem... After I replaced the multi switch, and the blinker fuse thing, still had the problem.

I had checked the fuses about 5 times.. I guess I missed it, but a 15 amp turn signal fuse was blown.

Check them again, very carefully.

Good luck.

where is the 15 amp fuse im suppose be checking? i heard there is one in the engine bay and under the dash, i havent checked them, mustang magic checked and said they tested everything. but i think im gonna do the checking myself, cause the multifunction switch is brand new and so is the flasher now! (just to clarify the flasher is that yellow box under the dash by the gas pedal right? any location numbers would be helpful

i have lights when i turn on my headlights by the way in the rear, except the left side the flast light closest to the license plate is out and the right side farthest one to the right is out, but mustang magic installed a new sequential tail light kit with the new harnesess i got! once again there is light back there just not brake light and signals or hazards! also i have no turn signals up front and on my guage cluster! this all happened i believe after i had my new eclipse head unit put in! and the stereo shop said they had nothing to do with it, but when i installed the flasher last night i noticed there is electric tape by the brake light switch i dont know if they cut something to get the headunit to be able to work while driving for navigation use?
