Question Heater blower motor repair?

Is it possible? I'm sure it's the bearings because it growls like a dog. I'd rather only take it off the firewall once. I don't want to remove it and find out I can't fix it myself.
If not, it goes on the Christmas list.

Re: Heater blower motor repair?

when I bought my 68 the blower motor would growl all the time, no matter what. so I pulled her out of the car, replacement motor in hand. When I got the factory part out I looked at it, and wedged under the wheel was a single pebble, I grabbed a screw driver and wedged that rock out sprayed a little silicone spray on the shaft and hooked a battery up to it.

Motor didn't squak at all, went back in and still works fine

Re: Heater blower motor repair?

Yeah... I wish it was that easy. I already had it apart... even bench tested with 12V. I must not have let it run long enough to growl when I tested it. Probably just wanted to make sure it worked.
I suppose it could be the cage wobbling. What a pain.

Re: Heater blower motor repair?

The deciding factor is if the cage can be removed from the existing motor.
If it can, a replacement can be bought and replace it.
Otherwise, its a whole assembly.
You might be lucky and find a set of brushes and bushings at Ace Hardware store.

Re: Heater blower motor repair?

If it is the rear bushing you can drill a small hole in the end of rhe motor and squirt some oil in it.
Personally, I would just buy a new motor.

Re: Heater blower motor repair?

Right....
The cage definitely comes off. I has the whole assembly apart at one point.
Thanks... I'll look for a motor.
