Electric window gremlins

[Iain C]

Ages ago my front windows went down on the switches but not up.  if I remember rightly I fixed this by swapping the wiring to the other (rear) switches and all was well, apart from the rears then did not work at all.

I got some new switches and thought this would fix the rears, however we are now back to the stage where they go down but not up.

Any ideas how to fix this?  Is there a control box or earth or fuse or anything that might be knackered?

Take off your door cards and remove the window motor, there is a small rubber grommet covering a tiny hole, fill it full of wd40, cures all disco window probs, I've done loads !!!

Which ones are 'they' now?

If the other ideas don't work then, to test ECU there should be 12v on both white/pinks on the back of the rear window console switch. If the 12v is there when at rest but drops very low on BOTH wires when you press the up button (up draws much more current than down) then definitely suspect bad joint in the ECU. If not then read on

If neither of the rear windows will go up, using either of the two switches for that window, but will go down with either of the two switches, then the only common point I see is the splice in the white pink wires feeding the console switches. With ignition on (pos 2) there should be 12v on both white/pinks pins 3 & 5 & GND (0v, -ve, earth whatever) on the black on pin 4.

Try shorting the two white/pinks together & try. If that works, look for the white/pink splice which, going by its number, should be in the console somewhere as the fault would seem to lie there.

If the GND is missing - well I don't think it will be cos otherwise the windows wouldn't go down.

If the short didn't work, press the up button and there should be 12v on the slate (grey) and GND on the slate/brown. If not then suspect switch

If yes then inside one rear door, with all switches at rest, (ignoring the red/brown lighting feed) there should be 12v on everything except GND on the black. With that door's switch in the up & console switch at rest, there should be 12v on slate, slate/brown & slate/orange and GND on slate/white.

If, that is I'm reading the diagrams properly  :lol:

Anyone know if it's in the same place on a RRC soft dash?

i would have thought it is, just pop the glove box out a check if the black is there!

Did you manage to fix it?

I resoldered the 1 bad joint in my borad today, which made the window work downwards only. Tried using a front switch (as its known to work) on the rear window and it worked perfectly, so going to order two switches.
