Citroen XM Forum

Hi All
Would like a bit of help diagnosing my non working drivers door mirror (97 XM V6)
The window is half up/half down
The small light on the switch at front is On
Am attempting to diagnose if it's the switch or other electrical before I start on the door panel removal
The switch has 6 pins...left to right voltage readings
Ignition Off
12.6. 0.09. 12.7. 12.7. 0.0 12.7
Ignition On
13.5. 13.1. 13.1. 13.1. 0.03. 13
Switch in up Position
12.7. 13. 12.7. 12.7. 0.02. 12.7
Switch in Down position
12.7. 13. 12.7. 12.7. 0.02. 12.2

Any pointers would be gratefully received
Thanks in advance

You need to refer to the wiring diagrams, as we need to know the pin numbers you have power/Gnd on.

For the drivers door mirror there shouldn't be any power with Ign off.

Grey connector Pins 1,4,6 and permanent Gnd, Pins 2,3,5, are Ign fed power.

Black connector Pins 2,4 and Grey connector Pin 7 flip flop to make the mirror motors move, one direction, or the other.

Thanks Dieselman
The mirrors are separate from the door window switch...they are centre console mounted switches
I will continue to test/see what I can come up with
Can't attach a pic of switch

I've just re-read the thread title, which says the window, but the thread post says mirror, which is the faulty item?

The window switches are pass through for +12V until one is pressed for operation at which point one +12v is released and shunted to Gnd via the centre pole of the switch.
Take a look at the wiring diagram, it appears complicated, but is actually quite straightforward.
