Re: 56 electric window motors

I suspect that what may be happening to a lot of these motors is similar in nature to what I am finding with most pushbutton actuator motors--the grease in the gearing attached is aged and petrifying and the motor lead wires are suffering from age and the isulation is cracking.
On the Pushbutton motors I now stock ample quanities of the four colors of 12 GA wire, including the elusive gray color (not that elusive, if you know where to buy wire) and every unit is completely dissassembled and all mechanical parts go through my parts cleaner, then re-assembled using modern grease. No one in the modern commercial auto electric business likes working on anything this small, they are used to motors the size of a starter, and complain bitterly about the conditions of working on small motors like the window motors.
I would try to take them apart and inspect everything, thouroughly clean and relubricate the gearing and replace the primary wires if they look marginal. If you are not comfortible doing the wiring find a shop that will do the work locally, or you could send me one to look at, I probably could replace those wires the right way (going directly to the brush and field connections as I do with the PB motors, no lazy shortcuts). Being inside the car's closed body those wires may be just fine, in which case leave well enough alone.
