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!
