If you have extended warranty on your truck take it to the dealer and tell them to fix it. If they give you a hard time take it back again and tell them either fix it or you will park it on their desk. It works. Ive had alot of rough times at the dealership for my colorado. Since feb of 09 ive spent about 20-25 hours in the dealership. Truck has spent roughly about 112 full days in dealership since I bought it.I fought with them everytime because they wouldnt do a damn thing for me not even a rental car
