I have a '77 with factory air. I am trying to get any feedback on replacing the stock blower motor / fan with something with more power... I checked previous threads on this subject and it seems there are others with my problem; low air volume from the unit. I have replaced the motor, checked all the ducts and diverters and sealed the inner fender/fresh air box on the passengers side and replaced the hood seal. The air coming in the car (on vent) is relatively cool. When the weather (and the car) warms up, it seems the stock blower (on high) just can't put out enough air to keep up.
My GM truck ('02) can produce a great volume of air from the AC. Has anyone tried replacing the original blower with a later model motor / fan? I realize the constraints of the original housing size. Just wondering?
