I am having trouble with my ac in 2005 GMC Yukon. The air just quit blowing out cold air. It still blows, just not cold. When I push the ac button, the motor does even drag a little like it used to when turing on the ac. Any suggestions? I checked the fuses, its not that

Your refrigerant is possibly to low or your compressor clutch went bad. You should have the refrigerant recovered to see if your low and have it recharged with the proper amount. On the same token if you add to much refrigerant the high pressure switch will kick it out.

Could even be a bad low or high pressure switch, due to the age of the vehicle being relatively newer it's doubtful that it's an electrical issue, take it to a repair shop they will know what it is in about 15 minutes.

The blend actuator has grease inside it on one of the electrical sensors. See how to fix here==> http://www.tahoeyukonforum.com/forum/showthread.php?t=17741
