We have removed the rear window switch to try and get it working again but now I have forgotten which way the wires went! I looked at the diagram in the tech info but unfortunately I cannot read the writing as the scan isn't clear enough. Does anyone have a clearer copy of the wiring diagram?
Rear window switch wiring
- Thread starter Zadkiel
- Start date
It has 5 wires, it is the rear right. They are green, black, blue, blue with white rings, black with white stripe.
Of course these may not be original colours, but if I can figure out what each should be i.e. positive, negative, on to next switch or whatever then the mulitmeter and I should be able to piece it back together!

I had the same question a couple of months ago.

Two wires come from the window motor, three wires from the front wiring harness.
The switch has the numbers on it to match the wiring diagram.
Good luck.

My bad. I thought you meant defroster switch. ( I heard rear window and pulled the trigger and misfired.):roll:
The wiring on a window motor works if you have original motors. If by chance you have the E28 motor upgrade the switch wiring is a bit different as the switch has to change the up/down connections vs. a direct wire and a ground.

All sorted now. Wires didn't match the diagram but I actually did a proper job testing the other side with my multimeter (I tried earlier but not comprehensively so failed) and applying the logic to the right, success! (after having to switch a couple of wires to make up up and down down!)
Still moves incredibly slowly though, will have to put the motor upgrade on the list.

If it's slow it's not a motor you need but rather a thorough removal and cleaning of the track and gear, followed preferably by a relay upgrade, both will do wonders for window speed.
