blower motor runs with key off
I've seen other threads about this issue and highly suspect the blower control module has croaked. Looking around on the web I see the part is common to 90 thru 92 with C68 (automatic) HVAC. Does anyone have a good module I can borrow to test my theory? Or an extra to sell?
Cheers, Glenn

Re: blower motor runs with key off
Mine started that this past week. Fine one day. Next day I turn it off and the blower motor keeps running with the key off. Through def. Cranked it back up and switched it to vent. Shut it off and went back to def running. Unplugged the blower so my battery doesn't run down. Runs down after 6 or 7 days anyway. Where did you get your module?

Re: blower motor runs with key off
Would a bad module also cause the blower to run slower than it should? And has anyone run into this situation before?
