Hey all, 78 malibu, originally ac, converted to non ac for space reasons. Recently my blower motor died (46 year old no suprises) i ordered a vdo/continental along with a new relay and resistor just for reliability. The old motor was confirmed dead by bench test. Anyway new motor just died. Things maybe an hour old?? Going to buy another one but i noticed options include ac/non ac and vented/non vented. Wondering if mine burned up by selecting the wrong replacement? Original was ac/vented so that is what i replaced it with, and just let the vent tube hang. I don’t recall what it was attached to anyway but it’s long gone. Should i go with the non ac/non vented or did i just get a dud ….
