Electric window motor issue?

[Andrastronaut]

Hello All,

I would like to ask a question which I did not find an answer to looking through google pages searching for specific Signum / Vectra C issues and also searching for generic electric window issues. Everything tries to suggest I have bad regulators. I don't.

So, I took the door card off, and with a multimeter I measured the voltage at the connector which plugs into the window motor. There is 12V (11.86 &11.84 to be precise - engine off) when pressing the up or down switches on both front doors. So the switches are fine, electricity gets to the motor. The symptom is, that the window would go up and down then suddenly change its mind and won't go up or down any more but the motor clicks. Sounds like when I had a bad starter motor once on a car and it was just clicking but not turning the engine. Would this work on the same principle? Can I just go ahead and buy a replacement window motor? Or would there be other bits to check I did not think about?

Also, the whole window regulator assembly is inside the door, riveted to it. However there are 3 holes where I can see three phillips screw heads, which I suspect is holding the motor. Can I replace it without drilling the rivets out and removing the whole regulator assembly?

I will be moving to a left hand drive country and the car is coming with me (had her for over 7 years now, we are one), obviously all the ticket machines...etc are on the left there so need the window working 100% reliable

Many thanks in advance!

Guys, any suggestions? I'm still having this issue. The window did not go up today, so I removed door panel, hit motor with hammer and then it went up so I need to take the motor out and renew it (have an electrician in the family who renewed my starter before).

I took the the 3 bolts out which are around the motor but it did not move and looking inside from the side, I can see the whole regulator assemble around the motor, so I think I will need to remove everything. There must be somebody out there who has done this before.

Thanks in advance

Hi I have been checking for you and it appears you will need to drill the rivets out and replace regulator and motor

is this right @plasma ?

As far as I can remember there are 6 rivets to drill out to replace regulator.

to remove just the motor theres 3 torx screws (T30 if i remember) you can leave the regulator in place, but make sure you grease up the necessary points while your in there. It is a tight fit, give it a good old wiggle wiggle and it will come away from the regulator... dont worry if regulator moves as motor will relearn the up/down positions when you refit it
