I cannot operate the right hand rear (right hand rear) power window using the switch on the right hand rear door. I can operate the same window using the appropriate switch on the master control panel on the drivers door. If I plug the right hand rear switch into the left hand rear wiring, it operates the left hand rear window correctly. So I assume that the right hand rear switch itself is not broken. If I replace the right hand rear switch with the left hand rear switch, I still does not operate the right hand rear window. In each case I can operate both rear windows from the master control panel on the driver's door. To me, it looks like there is a problem with the right hand rear wiring. But in that case, why does the master control panel switch work? I have tried to trace the wiring from the right hand rear door, but without success.
Do you
have the same problem?

Good morning,

Have you checked the rubber boot from the car to the door for any broken wires? Common area for wire harness failure.

Check the wiring diagram.

Thanks, Roy. I have found a connector attached to the harness where it exits from the door pillar. Could you possibly send a higher-res image of the wiring diagram, showing colour code? In particular, I would like to know what is the purpose of each of the different colored wires. The connectors are wired as follows (using the numbers stamped on the connectors):

Male attached to switch:
1 red with white stripe
2 black
3 red
4 yellow
5 not used
6 not used
7 not used
8 blue

Female from inside door:
1 black with white stripe
2 black with green stripe
3 green
4 blue with white stripe
5 red with green stripe
6 black
7 not used
8 pink

In the meantime I will test continuity between the connector in the door pillar and the connector in the door panel.

Hi, rivermikerat. Thanks for taking the trouble, but I am afraid that I still cannot read any of the text on that image. Is the 2carpros website perhaps 'downsizing' attached images? Can you send me a link to the original diagram? Sorry to be a nuisance. I have checked continuity between the connector in the door pillar and the switch in the armrest, and have documented the results according to color code, so now I want to try to relate those results to the schematic.

Managed to download diagram from Google. Was not aware that such diagrams were available there. I will post results when/if I manage to make any progress. Thanks to all for your assistance thus far.

Unless there is trick of which I am unaware, 2carpros website does indeed reduce size of images. To such an extent that images are practically unusable. However, I downloaded a schematic from google. That schematic identifies the RHR connector as K-06. On that schematic, K-06 is shown as having 8 connection points. On my switch, there are 10 connection points (1, x, x, 2, 3 along one edge and 4, 5, 6, 7, 8 along the other). Also, the colors are different. See attached images. Incidentally, what color is coded as 'L'? Is there a different schematic that I should be using?

Hi guys. Sorry to butt in, but you are overlooking the obvious suspect. Before you get "wrapped around the axle", swap the driver's switch assembly. The fact that switch works the window proves the right rear motor and all the wiring are okay.

There are four switches incorporated into the RR switch in the driver's switch. Two are "on" when that switch is released. Those are in the ground circuit when the RR switch is activated. One switch is in the circuit for "up" and the other one is in the "down" circuit.

Thanks, caradiodoc. I will hunt around for another driver's switch and see what happens. I would never have suspected that item, but your explanation makes me wonder. I will post my findings once I have managed to test as suggested.
