hey ht, it begain with my passenger side just completely stop working. then a year later my back left side window goes out to. i brought it to the dealer and they said itll cost 150 just to check it out. has anybody had this same problem or knows what to do??

 

sounds like either your window regulators or possibly the weather stripping. id lean more towards the regulators.

check the FAQ section, i think i recall seeing a DIY on fixing/diagnosing this problem.
