Blower motor rebuild
My blower motor keeps quitting but if I hit it hard with a metal bar, it'll start running again. After a while, it starts running slow so I have to whack it again. What's wrong with it and can it be rebuilt?

Re: Blower motor rebuild
there is probably a bad gear in there or a bearing that allows something to get away from what is driving it.. I don't know whether it can be rebuilt it depends on damages once you take it apart and the availability of parts

Re: Blower motor rebuild
I wouldn't even bother trying to rebuild it,remove & replace.I replaced the heater core in my crew last fall & did the blower motor same time,you can't put a price on a blower motor when it's -40 deg C.

Re: Blower motor rebuild
If you are looking for a "cheap to get me by for a while" fix, drill a 1/16" hole in the top of the "bump" in the middle of the end of the blower motor and spray a small bit of wd40 in it, run for a while then put a few drops of 3-n-1 or other light oil in it.

Re: Blower motor rebuild

The fun part is changing the fan itself. You have to reach down inside the fan to remove a clip that holds the fan to the motor shaft. Personally, I would rather spend a couple bucks more and get a motor with fan already attached.

Re: Blower motor rebuild
The blower motor and fan assembly come out from the engine compartment side.
Check to see if mice and packrats made a nest in the fan housing like they did on mine. It made a lot of noise with their crud in there.
