Passenger windows Don't work ??????????

I have a 96 Jeep Grand Cherokee Limited. My problem is the whole left side of the jeep windows work fine. The passenger side dont, I have change both side window switches and nothing changes. So I just got curious and put the master window switch from the driver side on the passenger window, and then the passenger side would work and the driver wouldn't. Please help

Disconnect the rear switch and see if the front works then. Mine did the dame thing so the PO took out the rear switch so the front would work.

I decided to tinker one day, the switch rattled ao I took it apart.
There are two wide-V shaped pieces of metal. They had come loose so I put them back on their pegs and the switch rocked back/forth smooth and no rattle.

To this day it still works

There is an interruption in the circuit somewhere.

Check for broken wires as stated above.

Both grounds for the front and rear door windows are secured with a screw to the floor pan just in back of the front passenger seat. Check to see if the grounds are good.

Ok I have check both grounds the one under the driver seat and the one under the passenger seat. They checked out ok. So the passenger windows still don't work, and my dash doesn't come on only the abs light.

I don't know how much electrical back ground you have, because your into a section of the electronics part of this beast that can get a little complicated without a diagram.

The two things that these two circuits have in common is where they recieve their power source from, and a communications link (body control module).

Fuse #11 in the PDC (under the hood) supplies power to circuit breaker #2 (power windows), fuse #7 (instrument illumination, and BCM, which controls communications for the power windows as well as the signals for the dash indicator lights to turn on.) CB2 and fuse #7 is located in the Junction Block (passenger kick panel) ABS light runs on it's own circuit.

If fuses and circuit breaker check out they might not be power related.

The right side windows can be controlled from the drivers side via the BCM but both right front and right rear are linked together thru the right front passenger window module located in the front passenger door. Check the twelve pin connector at the module, check the gray connector at the door jam, check the connectors to the BCM (located under the dash to the left of the steering columb it has mass of connectors going to it) there should be 2 white connectors going to it, one of them may be your bad boy. And check the black connector on the left front door jam. Good luck!

The dash light connector is plugged directly into the back of the instrument panel and can only be accessed by removing the surrounding bezels removing the 4 screws and pulling the panel out, the plug will remain inside the dash.
pin #1&2 is ground, pin #3 is power from fuse 7 , pin #4&5 is ABS light, pin #6&7 is turn signal, pin #8&9 communication links to the PCM, Air Bag Module, and BCM, pin #10 is dash illumination lights from the BCM.

Try some of that and get back to us.

Re:

Quick Question could a bad electric door lock(s) cause my passenger windows not to work. I have done everything mentioned above and everything checks out ok. I have even went as far changing out the harness under the dash.

If your able to operate the passenger side windows with the drivers side switch connected to the pass. side, would make me think that the pass. door module was bad. I don't believe the BCM is wired in such away that you can operate the driver's side with the switches reversed.
What's interesting is the dash lights aren't working either that would cause me to believe that the two problems might be steming from the BCM.
The locks also get their signals though the CCD bus (data communications link) from the BCM. Maybe it might be stupid to ask, but is the window lockout switch working?
Without a service manual w/wiring diagrams and diagnostics manual and DRB you might be just throwing parts at this until it works Try getting either a garage to diagnose the cause for a few bucks or borrow a DRB from buddy.
You also never said if the PCM was throwing any codes.

I have change the pass. side switch on both the front and rear. I have change out the bus and I get the same resaults. the whole right side is acting as if it is dead, but i have used a test light to check for power and both windows are getting power. I have a wiring diagram for the jeep and I have used it to check all grounds and there all secure. and the pcm is not throwing any codes at all.

I don't know if the circuits are the same but I had a very similar problem on my 04 wj where the large black ground wire was broke inside the rubber that goes between the door and the body on the driver side. The driver control would work but none of the controls on the other side of the vehicle would work. Apparently a common problem on the wj.
