Power Windows, what was I thinking! (update again!)

So I have been working on this 68 GTX that I picked up in the fall. Had the interior out of it, rebuilt the dash, etc.. Got it all back together this past week and crossed my fingers and fired it up. Everything worked! All the gages, switches, everything! This almost never happens!

The car has power windows. In my enthusiasm with how things were going, I cycled the windows. Big mistake, on the second time through the right rear window went down and now won't come back up. When the switch is toggled, there isn't even a drain on the ammeter. The other windows still work.

Damm...now I will have to rip out the back seat, etc. to get to the guts! Any tips or thoughts as I get started? I actually have a new NOS motor and new NOS single switch in my stash of parts. I did not rebuild anything associated with the windows prior to this

pop the switch off and take a jumper wire to try and get that motor to spin the window up.

I've got a car with power windows and I never roll my rear windows down completely because the motor's are weak..this lets me grab the windows and help them up when necessary

A lot of times, the gears that are driven by the window motor get caked up with a grease/dirt mix that makes it hard for the motor to work properly. If this is the case with your windows, cleaning and replacing with new grease will get them working like new again. However, you have to remove the motors to do it. Probably not what you really wanted to do.

If the motors were dragging due to stiff grease or binding or whatever you would register a load when cycling the switch..

No power it getting to the motor, it's a switch problem... The master & the single switch both can cause the window not to work from either switch... If you haven't touched the single chances are it's the master... If you have spare switches try swapping them out...

And when your done messing around & just want the windows to work every time..

Ok, latest...

I switched the single switch with a known good one...no change...no movement and no load on the ammeter. The other three windows work well.

I ran a volt meter across the switch. I am getting power to the single switch that shows when I toggle the switch with the meter on either the down or up wires and ground.

Now here I where I get confused. I tried to put a battery charger across the green up wire and ground. The charger tripped its safety circuit each time. On the gray down wire, nothing happened ( the window is down).

So I guess next is out comes the seat? In order to either jumper the motor or swap it? Remember this is the right rear. What a pain, nice new interior too!

I believe the motor uses just the two wires that change polarity with each direction you want motor to operate.

Got it, I'll try again
