I have a 1969 small block 350/300 with A/C. The original blower motor was replaced and it does not push much air into the car. When I change the 4-position fan switch there is a very slight change in air flow, but not enough for comfort. I looked through my AIM but cannot find an original part number for the blower fan. I have the original fan with the cooling hole in the side of the motor housing. The replacement blower is sealed and does not have the cooling hole. The replacement came in a plain white box with red panels - no manufacturer's name on it. The only markings are:
On the front of the box:
REPLACES 22020943
15-893
Motor
731-21R
On the bottom of the box:
1746 FE
72324
Can you tell me if this is a standard replacement part?
How important is the cooling tube and connection? The tube is missing, and it seems to be in short supply - unavailable.
Would either the condenser or the resistor in this curcuit be the cause of the fan running at very slow speeds?
Any other ideas?
Thanks,
