A/C won't stay blowing

Asked by Jun 29, 2013 at 06:30 PM about the 2002 GMC Sierra 2500HD 4 Dr SLE 4WD Crew Cab SB HD

Question type: Maintenance & Repair

My A/C comes on, but only stays blowing to your face for a few seconds, and then automatically shifts to your defrosters.  You can punch the buttons and redirect to your face, but again, after a short time it will redirect to defrost again.  This don't help when the heat is high.
