I just installed a window lift motor in the driver side rear door on our '89 Grand Wagoneer. I have 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, when I flip the door switches. 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! **** ADDED INFO **** When I used the test light and checked for power by flipping the switch in the door, I had power to BOTH wires simultaneously. This was with the switch flipped either up or down ... power to both wires. I'm assuming that since these are reverse polarity motors that I should only have power to one wire at a time, dependant on the direction of flip switch. ******************** Any ideas, please let me know!
