Perhaps your application of WD40 didn't help very much? I'd be tempted to try cleaning again to make sure all residue of WD is got rid of.

I agree!

One thing which has not been metnioned and I've never seen suggested as a cause of these problems, it the buttons pads themselves. For information - the black bit of plastic under each button is supposed to be sufficiently conductive to short across the contacts on the PCB. Oil/ dust/ WD 40 on those would be enough to stop the buttons working, so worth taking the time to clean those too.

Wear on those same types of buttons is a common cause of TV remote controls failing.

The black bits are used for the windows. Metal is used for the mirrors as it is actually powering the mirrors dirrectly.

I would take the top off the switches again, and then go back out to the car with just the bottom half and membrane. Plug it in.

Then press the nobbles for the mirror. For each dirrection there are two, and you need to press both down for the mirror to work. See if you can get any life out of the mirrors. If you can then you just need to clean it up well off the car.

DON'T PRESS UP AND DOWN AT THE SAME TIME THOUGH. OR LEFT/RIGHT

Remove any residue of WD40.

If you have time I would wash the membrane with a small amount of fairy liquid and dry well, to get rid of wd40.

You don't say what model of 75 you have, I am just wondering whether the basic model even had electric mirrors?? Someone may have had a new (secondhand?) switch module. If you have a multimeter you could check whether power is getting to the "live" side of the switch. Fuse 11 in the passenger compartment powers the mirrors and fuse 35 if they are also heated.

Cool Removing the switch..

Hi guys, can't seem to find any guide here, but how do you safely remove this switch?

Do I need to take the door panel off? Or will it just pull up?

Thanks

Its the plug connection that goes into the mirror. The pins in there are gone by moisture.
You must make a bypass wirring and than it wil work.
I had 3 rover 75 all of them had the same problem.

Doesn't seem correct for me, they both work fine going > Down. However to get it to work going up I have the wiggle the pad and they move up, don't go left or right though.

Just need to know if the door card control will simply "pop off" with a screw driver or if I have to attack the door card to get it out?

My electric mirrors have "frozen" before - just through not being used - sometimes some manual "help" to move each one left,right, up and down does the job, plus, holding the finger on the button.
Once you've got them working, do a weekly test to ensure they work when you need them.

I think it's the contacts because going up is rather hit and miss with the wiggles. I've read elsewhere that you can run a credit card around the unit and it should just pull out from there?

Will attempt later.

FYI, Tried moving them manually, they won't budge - gave em' as much pushing as I felt I could get away with, without breaking anything behind.

Also note to the guy using WD40, you crazy?
