2007 Silverado AC vent driver side hot

[Ski276]

My 2007 drivers side ac vents won't get cold while the right side cools very well. Most of the time it is ok but once or twice a month it just stops cooling,  even while driving on the highway. Looked for the HVAC-ECAS FUSE and don't have one. Help!.

Probably blend door motors failing. With a good scan tool you should be able to pull "B" codes in the HVAC module that will tell which motor had the issue.

 

My '07 did this a couple weeks ago during a trip to NC and back from MA. The passenger side was blowing hot. A key cycle at the gas station fixed it. Eventually it will fail completely.
