We have an 05 colorado 4 door,passenger side front window sticks, have to push down on it while pressing to roll up. Until tonight that worked.
the bell that tells you the keys are in the ignision, goes off when they are not. we have had few problems, one with the drivers seat,but the big one,we were haunted by the sales person to buy the extended warenty, which we told them we just do not have that kind of money right now.We kept getting calls and letters. Then we were actualy told that they could gaurentee us that when the warenty of 30,000 miles was up,we would start having trouble.So we could not aford to not get the extended warenty. We went in for a free oil change, and now have a squealing that keeps getting louder and louder.Driving me crazy........
