I had numerous problems with this vehicle (almost through my third set of tires, oxygen sensor going at 46,000 miles, rust beginning at 38,000 miles {car was two years old}, and the battery going prematurely). Last week, I attempted to put on my rear defogger. The light came on, but my rear windshield was still fogged up. The defroster also does not blow cold air if the car is in park.
The rear defogger does not work. Nothing happened, it just quit working. When you push the rear defogger button on the front panel, the light lights up showing it is working, but it isn't working on the rear window. It is hazardous because you can't see out of the rear window with frost and even snow built up on it while driving. I find this a big big problem when I cant go far snow builds up to fast. One other time the wipers stopped for no reason in the middle of my view. When I stopped at the gas station I shut it all down went got a pop came back out and started the car and then they started to work again not a good situation.
