Grand Cherokee window motor

[Huntington Guy]

rear pass window works sometimes, other times, not so much. Doesn't matter if I use the switch on the drivers door or on the actual door so I'm figuring it's the motor not the switch.
Im out of my element on most things car so any advice would be appreciated.

Another problem with that jeep? Shesh

[Huntington Guy]

Did I mention Jeep sucks?

Oh, and I bought it from guess where.

[Heartlessmcfly]

Yep...

Does it not work or just run slow?

Running slow would probably be your window regulator wearing out, dirty window tracks, out of line window, etc.

Intermittent functioning of the motor itself means you have to replace the motor and I wouldn't put the window down anymore.

But if you get stuck with the window down sometimes you can get it back up. Have someone hold the window switch in the up position and rap on the bottom of the door with a mallet or dead blow hammer. Sometimes you can shock the motor into working.

It either works or it doesn't. Sometimes it's fine for a few days, other times it craps out for a week or more. When it works, it works fine. That's why I figured the switch.

The power would run through the drivers door switch no matter what door switch you use. You can try taking out the switch and cleaning it. It's usually not that hard of a thing to do.

Actually cleaning is better than replacement in some situations. Some newer cars have to be programmed when you change the driver switch pod. I know it was like that for my 04 Suburban. (power fold mirrors and such) I took my switch out and cleaned and greased it and didn't have to go to the dealer to reprogram anything like I would have if I replaced the entire switch assembly.

On my cars the drivers switch feeds the other switches. Both have to be good. you need to test it with a voltmeter or test lamp. Once I had to replace the drivers switches due to a bad contact. Another time after 7 years I found the connector assembly was never locked into the drivers switch assembly. In any case you should test the switches before you throw money for a motor. What year is this Jeep

Replace drivers switch cluster, i doubt its the motor.

If that doesnt work, shoot me a PM, its how I make a living.

Thanks. Hoping to play with it tomorrow. Was out of town all week so car has been parked.

May be bad connection or loose wire. Always check the ground wires.

What year Jeep? 1990-2000s Jeep were know for wiring breaking in the boot that connects the door to the jam. I had to go in and repair all but one of mine, slice the wire and extend it, problem went away. Same repair for the door locks and speaker wires so check those while there. When seeing your issue, wire was broken but still together enough that will start or stop working when the door is opened or closed. Eventually it completely breaks.

It's a Jeep thing, enjoy.

Try having the key ON and while standing outside of the Jeep move the drivers door from the closed(Thu the open window) to wide open position while holding the window switch if it operates in a certain spot your harness has a broken or fraded wire . Can't hurt give it a shot .... As stated above power comes through main drivers switch . Good luck. Tom.

I had similar problem with the wife's jeep. The drives side window would go down and it took forever to go back up. The replacement cluster was $150. Screw that, that's ammo money. I pulled the cluster out and opened it up. The contacts on the drivers side switch were dirty. I cleaned them up and problem solved.
