A/C Issues STILL ONGOING

Thank You everyone for the feedback. As I said this is has been an ongoing annoyance over many years. The truck has been to 2 seperate chevy dealers, 2 firestone service centers several times, a repair shop that specializes in trucks, and from all the invoices it appears that every part of the a/c unit has been replaced. The last mechanic to work on it, swore he had it fixed and claimed that he drove it out and thru the city and it worked fine. BS! I appreciate the comments. Will be discussing this with the mechanics at a new shop in hopes that we can come to final diagnosis, repair.

The problem with the places that you mention is that every one of then use a machine to do the service. The Techs are trained on the machine and all they do is punch in what vehicle it is hooked to and the rest is done by the machine. They have no clue how to read the gauges and if there is a problem somewhere in the system the machine won't tell them. Try and find a garage where the A/C tech actually hooks a set of gauges to it and reads them. There is certain readings he will look for and times these readings are happening. A lot has to do with temperature and humidity. Good luck and follow up with what you come up with. I bet it's something simple that all the other techs are overlooking because they don't know what to look for.;)

BTW, running down the road your system should be blowing around 33-38 degree air once the cab cools out and you are running on Max mode.
