Is it just me, or can't you turn new window motors? I have 4 replacement motors, and I finished putting one back in...all the door lift pieces were taken apart by the previous owner, so it was a bit of a challenge. When I got it all in, i assumed i could position the track where I needed it and the window motor might turn. Any insight. This is the first time I have every messed with power windows. I knew I wasn't looking forward to it! Thanks,
I think you're asking if the motors can be turned with elbow grease rather than electricity? I'm gonna say no, because of the rather steep ratio between the drive and driven gears. Devon
The power window has two wires going in, both positive for the up and down movement of the window. The negative or ground is when the metal part of the motor housing around the gear is contacting the window regulator. Im not sure what your problem is but I had a problem that the windows motors wouldn't work and its because I wasn't completing the circuit. To test them simply plug the wire into the motor and hold the bare metal part of the motor to a good ground, then try your switch. Goodluck :TU:
Be careful! I assume the motor attaches to a regulator with a built in spring. My experience was that you have to preload the spring to help the motor lift the weight of window. Tricky to do and if that sucker lets loose it's like a guillotine. If you haven't done it before get experienced help!
Roger also has a good point. The window works just like a garage door in the sense that it needs the springs to aid in lifting and decending. The spring is under the most load when the window is down, just like if a garage door were down. If the window is in the closed position it will still have a load on it, not nearly as great as when in the down positin but still pretty good. After you remove the bolts holding the regulator from the door itself you can unbolt the motor from the regulator. Once those bolts are out is where it gets tricky, if you wiggle the motor free from the regulator the tension from the spring will be released and the regulator, usually the gear side will come down on your arm. Now it doesn't hurt but there is quite a bit of pressure to overcome. Upon removing your arm the spring may jump because its fully released and then it should be over. Reassembly is much easier, not to say this is hard. But you don't have to worry about the spring letting go. Goodluck :TU:
Don't know what year your car is and designs change, but what I had to do on a 60s model was to preload the watch type spring in a jig on my bench before I installed the motor/worm gear drive. I turned the scissor mechanism about 1 and 1/4 turns and held back the spring tension with solid stop and then installed the motor/gear drive which because of the high ratio can then hold the spring in pre tension. After installing back in the door you can then use the motor to position the mechanism where you need to get the window back attached. Not a job for a beginner unless you maybe have an experience guy help you out with the first one. CAUTION AGAIN! When you get that sucker preloaded if it lets go you can loose a finger. Ask any old mechanic. Check how many fingers he has left!
