Blower Motor Rebuild?

[Franklyn49]

I did a number of searches with no definite results...

Is it possible to rebuild a dead 6 volt motor at home?

I read that some people have "rewired" theirs etc. what does this entail?

would love to get get some heat and air flow into the plymouth if there is a fairly cost effective solution.

I just rewired my defroster motor. I replaced the two wires coming out of it (one to the defroster switch and one to ground) because they were badly frayed. It was a bit of a challenge getting it apart but once you do that, it's pretty straightforward. I unsoldered the original wires from their connection with the motor and then soldered the new ones in their place. I would think the heater motor wouldn't be much different. I did clean the commutator head with very fine sandpaper and lubricated the bushings with a light oil.

What is it not doing??? These motors are pretty simple and pretty stout. I have the model that is self contained. mine was turing very slowly, I gave it some penetrating oil around the shafts bushings, let it sit a couple of days, then gave it a short jolt from my 12V battery charger. After a couple of sessions of that it freed up and now runs just fine on 6V with just a slight occasional squeel on low.

sounds fairly simple to add new leads and clean the unit up, but mine isn't responding at all to power.

Wondering if the motor is in fact burnt out? and if so is it repairable? some have mentioned "re winding" their original 6v motor to 12v. I dont want to switch to 12v, but is it possible to do this to refurbish as 6v?

Tap it a few times while the leads are hooked to a battery. The brushes may be a little stuck.

When was the last time the motor ran? Niel might have a point.

I've been driving the car very regularly for the past 2 years and the motor has never run. I'll try giving it a few knocks while hooked up to power and see if that does the trick.

If it DOESNT work, does anyone know how to rebuild a small motor like these?

[Joe Flanagan]

I know that for both my starter and my generator, a rebuild meant mainly new bushings and brushes. With the starter, the bushings can wear to the point where the armature makes contact with the inside of the case and it will not operate. Don't know if this could be an issue with your heater motor but I would remove it and take it apart and see what's what.

whats to rebuild??? If the brushes are good, and the bushings are good, it should work, assuming that the coil wires in the armature are in good shape.

Have you checked to see that it has power??? In the discussion so far you haven't mentioned wheter the motor is getting juice or has a conection to ground.
