2010 GMC Sierra AC
My 90k miles 2010 GMC z71 has a weird a/c problem. It blows cold then blow warm and humid, a/c is full of freon (evac and recharge done few months back at dealer for same problem (out of warranty now). I broke my tech 2 last year. It has digital climate. When it cycles to warm the auto controls shift to outside air, I press inside recircle and it blows frigid again. I have no known fan or water temp issues. Drain has been cleaned. No pressure readings to post.
Any thoughts?
