Lose the engine - it sounds tight. AMC , i've heard, have low bids on items that are costly, and those motors and the power seat motors get slow over time. Bushings / worn contacts / cheap material etc. Eventually I'll find the GM engine that will swap into the AMC - easier - stronger - cheaper to replace. Check the lift mechanism for binding when the door panel is installed - you'll need a can opener to remove the outer skin of the door. Brien.

To: mail@xxxxxxxxxxxx I just installed a window lift motor in the driver side rear door on our '89 GW. I've got it all installed correctly and it won't move a bit by using either the front or rear door switches. I've cut and crimped the wiring harness connector onto the rebuilt motor two different times, using two different connector types and it won't budge. I've hooked up a test light and tested various locations for power and have juice through the wires. The only way I got the motor to work was using my battery charger on 2-AMP 12 Volt charge setting. I took the wires directly out of the motor and hooked them up to the charger and powered it up ... the window motor would operate fine then (slowly on 2-AMP service). I'm guessing that the short wire-harness might be bad below where I tested it, but am looking for any ideas from you guys on this one ... it's got me baffled! Any ideas, please let me know! Thanks!
