Hey guys,

My RR window is stuck in the UP position.

1. When using either the driver's switch or the local switch for this window, I get no action at the window (no window movement, no motor spinning).

2. I tested the voltage at the harness for the window motor and I get 12V when the switch is in the UP position and 0 when the switich is in the DOWN position. ( I only tested this with the local switch)

Does this mean I need a new switch?

I plan to connect the motor to the battery before I get a new switch to make sure its not the motor.

I don't believe this is a regulator issue, correct?

Ok guys,

I reversed the polarity at the wire harness for the window motor (disconnected the harness and crossed the connection using two new wires).

The result was that pressing UP on the switch enabled my window to be rolled down, so I now know its not the motor or regulator and mostly likely the local window switch.

Best place to buy one of these?

Im having a similar issue on my XJ. I could only get the window down. I did the same thing to get the window back up. Im going to the junk yard to hopefully find that switch.

You can find them a your local junkyard. I have also seen them on ebay.

MirageMobile

Well,

I went to Autozone and tested out a new switch and achieved the same results, so it has to be a wiring issue.

Both switches will raise the window just fine, and lower it if I reverse polarity at the window motor harness.

Sounds like my switch could not be getting power for its DOWN position.

I guess I will start looking for a broken wire but am not sure where to start.

From Joe Peters and well stated. Sounds harsh but just makes sense:
"Let’s play a game.

You pretend that you are the only one that knows what year/engine/model, etc that you are asking about.

We will all pretend you never asked a question until you provide at least the bare minimum of information about your vehicle".

What the hell are we working on here?

MirageMobile

Haha I agree with that one and internet forums, Cruiser

I made two assumptions,

1. That the vehicle I am referring to is a Jeep Cherokee since the URL of this website is www.cherokeeforum.com

2. That the title under my name stating "1999 Jeep Cherokee Sport" and some details about my vehicle existing in the "garage" would clarify what year and model of cherokee.

From now on, I will specifically state these details in the first sentence of my inquiries.

I purchased this jeep 3 weeks ago.

It will be my first vehicle to become both mechanically and electrically "enlightened", as I have little experience in automotive repair/maintenance.

What else can I provide to clarify what we are working on here?

Current status:

1. Activating the local window switch supplies 12V in the UP position and 0V in the DOWN position (measured at the window motor harness)

2. Activating the driver's switch for the window of interest (rear right) supplies 0V in both the UP and DOWN position.

You're dead on - it's definitely a wire.

I had the exact same problem with my rear passenger door, I reversed polarity and everything just like you did so I knew the regulator worked in both directions.

Turns out it was a broken wire in the driver's door boot. I repaired the wire and now it works perfectly.

If I remember right it was a dark green wire - but don't quote me on that. I've also recently repaired my door speaker wires so I could be mistaken.

So yeah, check the wiring in that boot. I can almost guarantee that's your problem.

On my 94 all power comes from the drivers side power windows box. The lock out switch opens the circuit so none of them get power.
Also ground wire for the power windows runs underneath the carpet in the front and mine was so worn off that the wires were cut (open circuit to all other switches, I could move them up and down from drivers front switches).
I had to replace all the wires in the area where they go from the door to the Jeep. Opening and closing the door bends them a little every time and they will break. You can try holding the switches and closing and opening the door to see if it does anything. Those wires in the sleeve from door to body where already fixed with butt connectors 3 times in my Jeep (OEM wire-connecor-wire-connector-wire-connector-OEM wiring). It all fell apart when I took the sleeve off so I cut the bad wiring 1 at the time and soldered in new piece of wire between door and body for each one.
I can post wiring schematic for a 94 later. A 99 might be different.

With the help of some wiring diagrams, I was able to solve the problem.

the front drivers door had atleast 3 "repairs" by the previous owner, so I went in and fixed those properly.

The rear right power window wire had fallen back into the door/kick panel and was located and patched as well.

Sorry for all the posts guys, I just found it useful for me to use as a journal to track my progress for fixing this issue.

Now onto the front speakers!
