rear driver side window quit suddenly

[Bosox Al]

my rear driver side window quit suddenly, and i have never had problems with it before. I checked the switch by swapping it to the other side and it worked fine, so then i checked all the wire's coming into the door and there were no breaks. Then after shutting it one day my son hit the switch and it went down. So when i went to put it back up it would go up but not down i did it slowly to see how far it would go and it would only go up. Now still nothing up or down. anybody deal with this before??

The front passenger window on my '84 is doing the same thing now. The window will go down if I hold the switch down and bang on the panel with my fist so I figure it is a mechanical, not electrical problem. Yours sounds like it may be electrical or poor connection but try banging on it first. Lithium grease is good for lubricating the track.

ok i took all the mounting bolts that hold the piece that holds the window motor to see if i could wiggle the yellow and green wires conected to the motor for a bad connection.well when i pushed the switch it went up on the slack that was there from the bolts being missing. nomadder what it didn't go downat all butt instead used all the slack up that was there, does that make sense???? Well it will go up but not down sop how do i get it to go down. is the motor bad? do ihave to take that all out? and if i do how do i do that if i cant get the window down???? Any body have this prob before???

Sounds like a bad motor.Just tape your window up to hold it in place and then remove the 2 bolts that hold window to regulator. Remove regulator bolts and remove through large opening at bottom of door. Fairly easy job.....you just need a figure 8 screwdriver for the bolts. Good luck!

These switchs are not very good, and they are definetly not water proof. There is likely corrosion on the switch contacts.
You can try my old trick and use some pressure inward on the switch as you actuate it.
If that does not work then disassembly and cleaning the switch is about the only option, short of replacing it with a new one.
You will have remove the switch from the door to do that. There are a couple of small metal tabs the hold the switch in place, if I remember correctly they also hold the switch together, remove them and use a pocket knife to pry the switch apart. Once it is open you will see what has to be done. Use a small stainless steel wire brush and some contact cleaner from Radio Shack. Reassemble and you should be back in business.

I checked the switch and also moved it to another door an it worked fine plus i tried one of the door switches from the other door that had no problems. I think this might be a motor problem but not sure.

IT'S POSSIBLE THAT THE MOTOR WILL ONLY WORK ONEWAY...HOT WIRE ...TO SEE IF IT GOES EACH WAY... ......ME!!! ;)

i find now that if i slam it shut enough times i can get it to go down but then it eventually it will only go back up, until i go back to slamming it again.

My drivers rear window is a little finike too. My daugter found a sweet spot to hit it to get it to work. Kinda like the Fonz. She smacks it in the top right corner of the glass from the inside.

Just thought I'd pass this on.

When you hot wired it did you also ground it? You might have a bad ground, but my guess is the motor.
:cool:

I'd say most likely, bad motor.

Just had the window motor gremlin on my 88. The motor does not have a seperate ground (Just two wires). You put positive to one side and negative to the other it moves in one direction. If you reverse your wires it goes in the other. If you take a part the door you can access to wires for the motor directly and see if it is the wiring to the motor or the motor itself.

Here's a new suggestion. When I got my 89 GW last year the right rear window wouldn't work up or down. Took the door handle, armrest, and panel off and then it worked fine. Put it all back together and nothing! Took it apart again and it worked. :mad: Finally figured out that it was the screws that hold the arm rest to the door. The PO must have replaced one of the screws because it was longer (and not torx head if I remember right) than the other one. If I tightened it all the way it must have caught on the window somehow. Got a shorter screw and problem solved. :D

[Bosox Al]

first i appreciate all the ideas but, i don't know the first thing about hot wiring, and on the screw thing, already did that last september with the door handle.I unfortunately think now that it's the motor or a bad ground but... how do i check the ground????????

[Bosox Al]

It's all good , turned out to be a broken wire in the door channel. Thanks again for all the help and suggestions.

MR. BO.....THANKS FOR LETTING US KNOW THE OUTCOME...GARY smile.gif

I don't have power windows in my FSJ, but have done a ton of power window repairs on "other" model cars and trucks. If the FSJ has a master control on the drivers door that controls all the windows then their wires all go through that switch. Check the wires that go through and into the drivers door. These wires get flexed the most and often break causing one or all of the windows, door locks to quit working.

Usually when the motor quits it wont work at all.

Hope this helps!

I forgot to mention it, but Shane's reply rang the old bell, he is right that all the wire feed through that front drivers side switch. There is also a repair bulletin in the MR253 maintenance manual about the the wireing fraying and being damaged at the drivers side floor board under the carpet and under the seat belt retractors. The bulletin says to remove the clips and check the wireing and tape the wires down with duct tape. It said that this causes inoperative power accessories on both the left and right sides.
The gound thing is more than likely a switch thing, I say this because in order to change the direction of motor rotation, you all you do is reverse the polarity of the wires. That is what the switches do.
