Wiring diagram for for 1988 jeep grand wagoneer rear tailgate window motor

Has no relay . Has rear wiper module , part of the motor assembly . Check fuse's # 8 20 amp an #3 10 amp . the wiring diagram just show's junction block , must be inside fuse box . Check it out here http://www.bbbind.com/free_tsb.html free wiring diagrams .

I suggest check this information in your Jeep Grand Cherokee ZJ-Secc-8W-Wiring-Diagrams Service Manual.

Hope helps (remember to rate this freen answer amd leave an testimonial).

I'm assuming your question deals with how to route the belt...
There is usually a belt routing diagram near the radiator...

Before you get started, please review this article: Where's The Fuse?

Then, I can't give you any real good information about your vehicle because There is not enough information available. I would need to know YEAR, MODEL, ENGINE SIZE, TRANSMISSION (Auto or manual, Overdrive or no overdrive, 4X4 or 2 wheel drive) The wiring can be completely different depending on these things. The only thing I know from your post is that it is a Jeep.

There are at least, 2 fuses associated with your radio (some models have 3)

If your tailgate window is electric, the problems could be related, but I think this to be pretty unlikely. If it just doesn't latch, there is most likely something wrong mechanically with the latch itself. Sometimes the latch mechanism gets closed with the window open. In this case you would have to operate the key or window release button or lever whilr opening the catches on the latch. Then when you close the window it will latch properly.

the original owners manual has a fuse diagram. I have had good luck with the support at autozone repair website. If this is about the fuse for the rear window wiper try a fuse that is 5 amps higher than the one that the owners manual recomends. you will still be fuse protected but the slightly higher value won't blow under normal load.

have no idea of resistances i just hot wire these things to test ,your getting to technical here ,if no power to motor then check the wires inside the rubber boot that goes from the rear tailgate to the body ,this is a common fault as wires get trapped and broke

bad window motor or window regulator or both.

The ground has corroded off the sending unit.You can access this by drilling out the rivits in the access panel under rear seat on drivers side.

I don't think you need a wiring diagram.
Jeep had alot of problems with the lock accuator in the tailgate.

Check in your user's manual for your fuse location on the rear windshield wiper. These grand cherokee's have electronic actuators in every door. Inside these actuators they have very little motors and move everything via plastic. Very bad design flaw, as most of these actuators are 300-400 dollars to replace. You can find ones in salvage yards for 50 though. On your rear hatch, the door and the window are run by this actuator.
