Hi, I am changing out the window motor in a Buick lesabre. When i put the new motor in place and push the up button it goes down about 2 inches, when I push down button it goes back up. When I pull it out of the door, Up works up and down works down. What am i doing wrong?
Thanks
Chet

???? You put it in and it tries to work backwards of request and then take it OUT AND IT WORKS?? Can you explain that? If rebuilt some could just have the wires reversed or it was your call to put the right wires back to the right color.
Could you explain that situation better?

I bought the motor new at auto zone. When I first hooked the new motor up,outside of the door, and tried it , it worked like it was supposed to. Push the down button and it travels all the way to the bottem of the track. Push the up button and it goes all the way up.
I installed it into the door, the guide into the track on the bottem of the window, lined up all the holes for the motor and track, bolted them in place. Hooked the power up, just like I did when I tried it out of the door, and it works in reverse. I didnt cut any wires, just unplugged the old motor and hooked up the new. Didnt change any wires in the switch either. I tried working on it forever yesterday with the same results, just my luck I guess.
Thanks for your reply and input, and thanks for your time.

These things can be screwy. The same motor works either direction based on polarity. That for two wire motors. One wire is hot and the other is ground. Reverse that and the motor turns the other way which is what the switch is doing. When the make these motors they are usually left or right sided for the sides of the car and either a head on the motor or the wires need to be reversed or both. I've done tons of old Fords and change the heads with the gear for the specific car or side but end up switching wires for some - this with old cars and unavailable new parts.
If the motor has 3 wires it's a different beast. I thought they stopped that in 1965! Your switch itself should not be the problem. If you need to test it reversed do it with jumper wires as the test so you can return the motor if in fact it is wrong,
