2012 CTS Coupe HVAC Blower Motor Just STOPS!
 

Hi everyone. My 2012 CTS Coupe's HVAC Blower Motor just STOPS working sometimes (as in the motor completely stops blowing air). Usually it happens when I have the AC on its lowest setting (60 degrees) and then press one of the Climate Control buttons (Temp Up, Blow On Face AND Feet, Recirculate, pretty much *any* HVAC button), although one time it did it all on its own as I was driving. It either turns *itself* back on in anywhere from a second to a couple of minutes, or when I start pressing more HVAC buttons. I took it to my expired-warranty mechanic who plugged in his OBD-II Reader/Controller and there were NO HVAC-related faults registered. Has anyone else ever had this or a similar issue with their CTS (or ANY GM vehicle as I'm sure everything involved is also in MORE GM cars)? Thanks to anyone who can help!
