My 03 Silverado has ice cold AC until I shut it off and let it sit a half hour. At this point on really humid days the compressor will not run. AC then of course blows warm. This has been repeating for 3 years now. All works fine till I really need it on a hot and humid day into the 90's temp. So it does work when I first get in and drive. Its when I use it a while and shut the truck off for about 1/2 hr.
Any ideas please post.
thanks
