Advice- windows

Post by bigwinn » Wed Oct 13, 2021 9:17 pm

Hi all

I’m sure a few of you will have encountered this before so a view please:

Drivers window not working. No noise, nothing on press of the window button.

Is it best to start (once checking the fuse!!) with the switch, or assume it’s the motor or the regulator/guides

Tell me your stories for when I get the door panel off!!!

Cheers

Stuart

I have no stories, but is it possible to bypass the switch?
Maybe battery wires across the motor? Or jumper wire across the switch terminals?
That would help point you in the right direction.

Does it drop a little when you open the door? If so, that would maybe rule out the motor?

No drop when I open the door- so thinking its power or motor at fault bud

Ah, so applying power across the motor may give you an answer then.

Will give it a go

Getting a relay click on switch movement so plenty to look at

So is the fuse before or after the relay on its way to the motor? I'm thinking the relay switches in the power so the fuse will be separate? Assuming you've already swapped in a new fuse just in case? I've had it before when a fuse doesn't look blown but is. Never trust the visual check anymore.

Just a couple of ideas… Have you tried operating the windows from the door lock, i.e. roof up/down? In addition to reading the error codes you could try ISTA or INPA to read the switch status or to operate the windows.

Mike beat me to it! Use INPA to read the switch status and/or trigger the motor.
Doesn't sound like the cable has snapped on the regulator so hopefully you don't need to dig I around inside the door!
