FWIW at idle my 01 Tahoe starts blowing warm air (especially in our
recent Texas 110* temps), there is a tsb on it to add electric fans in
front of the ac radiator/condenser or whatever it's called.
FWIW, they finally released a redesigned low pressure switch. At
least it's a different part #. We've been seeing a lot of these too,
especially on the Envoys.

GM installed the wrong LP switches on a lot of 2003 Tahoes and the like. To
get the correct switch, the (finally a good one) dealer went to a different
division (Technical something) and got the correct switch....They (GM
Technical....) indicated it was a special order/request and had to come from
them as it wasnt available or released through normal avenues yet....Anyway
it works. I have not had anymore problems with the A/C.
Before this I could not count on the AC to work and if it did, not for long
periods of time....
I was very pissed and went to many dealers to solve the problem. None of
them really cared or wanted to help....until I met the last one.
It takes a resourseful technical service person to want to help and they
Don't let them bullshit you.
