Has anyone had the issue with the blower motor staying on high speed? Had this happen the other day, unit was working fine with the fan in manual mode. Stopped the car for a short errand and started the car and the blower immediately went into high speed. No change from the speed control, all the other functions work OK as in switching from vent to floor to A/C to defrost, etc. Must be an obvious short to ground somewhere as you can actually push the "Off" button on the control and it still runs.. Ran the codes today and nothing comes up. The fan will shut off when the key switch is turned off... any ideas as to where to look next?
