My 2003 Pontiac Grand Prix driver seat has overheated...I left my jacket on the seat when I went to open the car door the whole inside was smoking and it had burned the sleeve off my jacket and the seat is a little melted and now my car won't start. this is CRAZY!! What could have cause this problem? Also i did get my oil changed the same day maybe they did something wrong because he didn't even charge me (kind of shady). The Monroe guy said "You use our services all the time, besides im too busy so just take you car."

I have a 2000 and 2002 Pontiac Grand Prix owners manual. Both talk about the heated seat option. Neither manual says whether the seat heater(s) time out, like the rear defogger, after say 10 minutes or so. Check all the fuses including the ones in the underhood fuse box. There must be a safety feature to prevent this from happening which has obviously failed. It's probably a bi-metal switch located in the seat cushion. According to both my owners manuals the seat heater(s) are protected by more than one fuse. This may be why the car won't start now. So check all the fuses. HTH. - Jim
