yes deffinantly the passenger sideYou were saying something about your heater core... and that will be the problem causing the fog... if your heater core is bad... is it also on your passenger side alot more?
+1 heater core. mine did that same thing. i got a new core tho.alright, then it's for sure your heater core. Mine is broken but it would do that sometimes, and that's it for sure. Really nothing to do about it unless you fix it or block one of the lines i think someone suggested on here?
