Default 96 jeep grand cherokee window help

Hello everyone,

Not going to bore you with asking for help on locating the issue with the windows (currently only the drivers side works) I can't see the wires well enough to find a break or how to test them (and i think its in the over head console anyways, I can kill all windows and the dash board by moving it).

What I need is a quick simple solution to at least temporarily fix the problem. I have the door panel off but I was hoping it would be as easy as pushing the window up until I could grab it and pull it the rest of the way up. But I can not get it to move might not be doing the right spot and did not want to put pressure pushing up on the window itself.

So if anyone could tell me how to get it back up without having to hook up power to it. Not sure how the mechanic did it but they rolled it up and then when I said I needed it down got it back down fast. But I need to be able to drive the jeep and lock it where I am at now.

Thank you all for your help.

The only way I know is to apply power to the motor with a jumper to a 12 volt source (battery). I can tell you the problem probably lies in the harness where it leaves the driver's side door jamb and enters the door. Broken wires occur there due to bending back and forth over the years.

The only other quick fix is to remove the two bolts holding the window to the regulator and manually sliding it up. Holding it there can be done with a prop (like a yard stick broken off at the length needed) placed inside the door beneath the window, or by jamming it in place with a suitably folded up piece of paper that can form a wedge between the window and the inside weather seal. Duct tape also works by holding the window up and taping both vertical sides catching the window and the door.

It's a wiring issue somewhere but I have not been able to find it. I had the whole wire harness off the drivers side door and they all looked fine but I have no way to testing them(not electrically inclined really).

know its not the switch as a new switch still has the same problem.

the reason i think the short is in the over head is because when it moves or gets moved it will kill everything for all the windows (including the ones still working now) and it kills the dashboard.

not sure how to apply power to the motor, the door with the panel off still has virtually no access for my hands, is there possibly a step by step or video for these vehicles I've not found one for this year or close to it so everyone that i've seen has all this room to do stuff.

so must be the mechanic was applying power to it then to roll them up and down.

thanks

I have 3 x '96..I found the issue is with the plugs and wires accesible behind the side kick panel..take it out and you will see a weird large semi-clear square plastic connector..all the big power wires go through it

use the 95 FSM to work out what color wires do what...pull the plug and probe them with a test light and verify what does what...even though all mine checked good, when I ran a wire from the power end to the motor, it would work go up or down

the fix ended up being jamming a wire in the offending female pin, and plugging them back together, running the alternative wire piggyback style to the motor

try the above procedure..could have taken forever to track it down, as it passed a continuity test on said wires!

the alternative would be a major re-wiring of the entire harness, eliminating ****ty wires and plugs, but a very big job

I really want to help you out with your window issue. I remember a couple of months back you were having this same issue. I take it the window issue has not yet been resolved? I wish I knew more about how the window and window motor mechanism works. I never had to deal with it and do not know what all is involved in how to make it work?

I think you could remove the window from the regulator mechanism and lift it straight up. Probably with a few bolts connecting it onto and holding the window. Prop the window up with a piece of wood or something. Then, gain access into the window motor and remove the main axle. You should probably be able to manually turn and crank the axle gears at this point, until the mechanism is in the window-up position. Reconnecting the window to the mechanism should now keep it held in the window-up position for you. I think...?

The common problem is broken wire(s) in the door jamb boot.

Mine was repaired by moving the boot, soldering in jumper wires and covering w heat shrink.

That was as fun as it sounds.

This topic shows my door jamb wiring repair.

Hello

sorry for the delay in responding was out of town with limited access to all things tech.

anyways, I've checked for broken wires I was not able to see any but my ability to look is kinda limited. I had taken it to a mechanic and told them the same thing its common for a wire in one of the door area's to be broken/not working they didn't see any broken wires but I also don't think they tried very hard on it. I know the windows can roll up and down not sure how they did it. they kept saying it was the switch but I told them the brand new switch i had in the vehicle did nothing different than the old switch so that was not the issue.

Odd thing is when I took it to them none of the windows would roll down or up. The drivers side was the only one working but then it quite too. after getting it back the drivers side has worked just fine but still nothing on the passengers.

I still think it could be in the over head console but also a wire issue sounds possible too as they just didn't quite one day, they started to work off and one opening and shutting the doors would get them to work etc.

But I don't know how to test them to be honest and not what to test. I probably have the tools I know i have some cheap tools but not sure what they are for.

but my biggest issue is getting into the space to do anything. I am not a small person myself and my hands are not small making doing stuff a bit difficult plus even though I try to do as much as I can I am also physically limited on what I can do and how long I can do stuff for, sometimes my back gets all bent out of shape just standing for a few minutes and other times I can do for hours (although losing a bunch of weight I ma sure would help).

the jeep is not my daily driver anymore (kia soul 2013) but when the soul had engine issues a while back I had to rely again on the jeep for a lot and i just want to get it back to be usable and secure. I can't put a lot in there because there's no way to secure the vehicle with the window that won't roll up.

I have the door panel off right now but to be honest that really didn't help much, still no room to really get into the guts of the door.

sooner or later I'll get around to checking out maybe the over head console and take it off and see what happens, if i take it off and everything works or i find a broken wire great problem solved although I don't think thats going to be the case, it would just be nice to get the window up at this point and now how even if not as quick or convenient as using a switch to roll it up and down.

If I knew more about electrical I'd be better off but I don't and all those schematics just confuse me even more and of course this year jeep has to have different wire locations and colors (still never even found the auto delay relay, can hear it clicking but can't find the dumb thing under the dash).

I think the problem area could be with the overhead console. It could be? You already have the new switch in the door. You and some mechanics have looked at the usual door jamb wires suspects, and neither of you found anything that looks to be suspicious in this area.

I know awhile back you were having the dash panel, door locks, and windows issues... and when moving around the overhead console this would kill off all of the functions and make the power windows stop working. I read about other people who were mentioning about having a similar type of situation with their overhead console. It seems some people were able to resolve whatever similar issues they were having by looking up inside the console and fixing some wires which were shorting out on each other or on the metal roof. Someone mentioned how they had a bulb which broke and was causing the same thing shorting itself out by touching on the metal roof. Other people did not find any wire faults with the overhead console. A lot of them replaced the overhead console with a unit from a junkyard Jeep, and doing this fixed all of the issues they were having.. a few of them being the power windows and door locks.
