I seem to have a problem with my rear passenger power window that's
really puzzling. I first noticed it when it would only go down, but
not up, from the rear door switch, and wouldn't move at all from the
driver's door switch. They were calling for rain, so I took apart the
door to disconnect the window from the regulator, and clamped it up.
So, I've been trying to figure out where the problem is, but the
wiring diagram I have in my Haynes manual (1999-2004) doesn't match
the actual wiring on the vehicle. For starters, there's 6 wires, and
the book says there's only 5, and the colors and numbers are all
different. So, figuring out what's supposed to be what is a bit of a
There's a connector between the switch and the motor, so I took that
apart, and measured the voltage there. With the switch in the down
position, I get 14 volts, as expected, and 0 volts with the switch in
neutral. With the switch in the up position, I also get 0 volts. So, I
assumed the problem was the switch. $40 and a trip to the Jeep dealer
later, I have a new switch, and the exact same problem. So, it's not
the motor and it's not the rear switch. There's also no fuse that is
just for this door, so it's not a fuse.
Anyway, I've taken some pictures, and have some voltage measurements.
This picture shows the plug that the switch plugs into:
And this picture shows the connector between the switch and the motor:
As you can see, the Green/White and Grey/White wires go to the
connector that connects to the motor. I think the solid green and
solid grey wires go to the driver's door switch, and the red/black
cables go direct to the battery, but I don't know that for sure. With
the car on, connecting the red and black wires gives me 5V, regardless
of where the driver's door switch is. Connecting the solid green and
black wires gives me 14V if the driver's door switch is neutral or
down, and 0V if it's up. That seems weird right off the bat. I would
have expected something more like 0V in neutral, 14V up, -14 down. So,
maybe that's the problem?
Anybody have any ideas or an accurate wiring diagram? What could be
Many thanks for any help!
