05 suburban Hvac problems...please help!
I went to shut off my suburban the other night and realized the fan motor was still running, next day battery dead, I was in a hurry that night. Jumped it and found the blower motor will ramp up and down with the dash control panel but it will not shut off when I turn it off. Shut off the ignition and the blower stays on the lowest setting. Any ideas?

Since I knew I'd be "responsible" if I did the repair myself - and I hate intermittents - and it's awkward to get under the dash on the passenger side - we took to the independent shop we've used for 2 decades. The fix was to replace BOTH the blower fan and the blower resistor. The mechanic was experienced with this issue, said his experience was that one being iffy would damage the other. So he replaced both to fix the issue.
Since I ask for the old parts, I could feel that the bearings in the blower fan had more resistance than optimum. But at 210K miles, that factory blower fan and resistor sure got a lot of use !!!
