Last spring, my passenger power window stopped working. I pulled it and found corrosion in the bottom of the motor. I cleaned, lubed, and reinstalled. Everything was great until this spring. Now both my windows have stopped working. I pulled the motors today, same deal.
The drivers side had the original rubber plugs in the bottom of the motor and a significant amount of water came out when I pulled them. The passenger side is really bad, and may not be salvageable.
Is there a trick to keeping water out of them? My window rubber is 2 years old.

So nobody else is getting water in their window motors? I know I'm not the only one.

I think the most common recommendation I've run across is to drill a small drain hole at the bottom of the motor. This would allow any water to drain out by itself.

Or just leave out the plugs...??? :wink:

Yeah, the plugs were out on one side. There was no standing water in there but the motor was still seized. The very bottom is the bearing surface for the shaft.
Does anyone know how the water is getting in? Is it coming in thru the regulator and the hole for the shaft?

I think the water wicks down the regulator and into the motor.

Of course the motor is the low part in the assembly. It collects water.

I drilled a 3/32 hole in the bottom of the motor housing. It will allow the water to drain out of the bearing. Working well for a few years now.
