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?

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

Just get a new one at AZ or OReillys, 25 bones and it will blow more air ;)

Price must have gone up. They're over $50 now.

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.

This is the one I put in my 83, kicked up the output of air ;)

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.

How hard is it to replace? Mine makes a nose at start up then quits , but annoying.

found one at CARQUEST for 18.39

The motor comes out real easy, 5 screws I believe, 1/4" hex head.
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.

I have my dash out right now, getting it recovered, I will check it out. Maybe it is the just the fan that is making the noise.

right below the motor, there is one with a fan attached. I will go for that one.
thanks

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.

Thanks for that. I assumed it was in the cab. :banghead:
