I've got a 2004 Trailblazer, which has been an excellant vehicle. I have looked through many pages of a/c problems, but haven't seen any like mine. We can be driving the TB and the a\c working good. Stop somewhere where the TB is shut off, come back and the a\c doesn't cool anymore. Sometimes can stop again and restart the TB and it'll work and sometimes it will not work. It always works the next morning though. The pressure is good in the system and the fan always blows as it should. Anyone else have this problem? I don't want to just start changing parts that don't need to be changed trying to find the problem.
Thanks for any help
