I have an 85 runner and just put the top back on and the rear window won't roll up. I know about the switch that is activated by the one of the bolts from the hardtop and it is working properly. I measured 12v at the connector at the motor and everything seems ok. I haven't used it all summer and it worked in early spring. My question is can those motors be rebuilt and repaired or do I have to replace it? TAP wants $100 and the dealer wants $250. Any suggestions to rebuilding or things to try that I might have missed? Thanks for the help. <IMG SRC="smilies/usa.gif" border="0">

Does the motor go up/down if you jump 12v and ground directly to its leads? (reverse them to go the opposite direction)

I haven't tried placing an external 12v to the input of the motor. I will do that tonight. Everything worked in May, took off the top for the summer and now it doesn't. Like I mentioned before, there is 12v going to the plug directly before the motor but maybe it can't handle the current draw of the motor for some reason.

my window is stuck in the up position, the tailgate is off the truck. Can I connect power to the motor and make the SOB go down so I can put the top back on?

There are two switches that will keep the rear window from operating:
1. Hardtop limit switch. Located in the hole for one of it's bolts, on the driver side right behind the rollbar. Sticking a screwdriver down in there will fool the switch.
2. Wiper position switch. If your rear wiper is not seated properly, the window will not operate. This is why the window will not work even with the hardtop on in some cases.

If both of these conditions are satisfied, the top *Should* work. Also, check out Roger Brown's rear window page.</font>

Even if you've got 12v, you still need a good ground to complete the circuit...

FWIW, I've had to repair several broken wires in the part of the harness where it flexes from opening/closing the door. Troubleshooting can be a PITA. <IMG SRC="smilies/frown.gif" border="0">

I mentioned jumping 12v/ground directly to the motor as an easy way to find out if the motor is the problem or not, if not look elsewere (obviously).

Yes. 12v on one motor lead, ground on the other. Reverse them to make the motor go the other way.

Ok, got the problem fixed! <IMG SRC="smilies/smile.gif" border="0"> <IMG SRC="smilies/bounce.gif" border="0"> <IMG SRC="smilies/bounce2.gif" border="0"> I took everything apart during my lunch hour and cleaned all the switches, grounds and even took the cap off the motor and cleaned the rotor and stator to ensure good contact. Put it all back together and gave it a try..... It Works! Must have had either a bad ground contection, limit switch not making good contact or poor continuity inside the motor, either way it works. Thanks for all you help and giving my some extra ideas to check before spending $$. <IMG SRC="smilies/beer.gif" border="0"> <IMG SRC="smilies/beer.gif" border="0">
