My '03 Silverado lemon has yet another problem. The AC is not working. I had it in several weks ago for the same issue, and the dealer 'repaired' a leak on the high pressure line. Now they claim the high pressure line needs replacing, and of course it will take several days for them to get the part. This velicle is a fiasco, certainly not what you would expect from a new truck.
