We are working on a 2002 Suburban with a 5.4, when the a/c is put on auto, or when you play wit the control the mode doors after awhile compressor will shut off, and compressor switch will flash, will loose the ground to the relay from the pcm, with scanner shows that switc is shut off, replaced control head, all a/c coponents are new. Sometimes will work fine for days, then wll go off. After about 30 minutres will work again.
