"Front blower motor 2010 yukon (AUTO HVAC)works perfectly. then will quit altogether for a couple of days before restarting again. Rear motor works fine. I have replaced the control head but motor went off this morn. Took it to the shop but it was working by the time i got there and they could find nothing to fix.

Is the power cable to the blower motor securely plugged into the unit? Is said cable frayed or worn?

Will check that out. Fairly new vech.

Very often the speed control module (if the Yukon is anything like the GMT360 systems I know well) down near the motor will have overheated wires in the connector and they start to oxidize and go intermittent. Heat damage on the connector and the wiring harness is pretty easy to spot when unplugged from the motor.
