HI folks-my 91 s4 auto[uk car] has a strange issue-when putting drivers window down sunroof opens,put it up-sunroof closes...
you can also open window/sunroof via the sunroof switch
disconnect sunroof switch -it still happens,disconnect window switch sunroof operates on its own
the switches are 3 wire[thick wires on window switch,thin wires on sunroof

is it likely to be a module issue?

Probably a module issue.

Try getting out of the car with the sunroof and window open - close the door then hold the key in the lock position for a while. Window etc should start closing one by one after 10 - 30 seconds.

Report back what happens.

will check and report back

which module would be the culprit for this and what would be its location please/is it the one that can be replaced with vag module 357 959 875? although i understand i may lose a function or two

one other thing is the car has been fitted with a clifford in the distant past
is it possible when bypassing the alarm functions they have joined a feed for both
-assuming it was an early total closure job..

the windows and roof dont close with key held in lock-although i am sure the sunroof inched closed a little the first time i tried it-no movement after that at all

Did you plug an extra plug under the seat you found unplugged? I did when I removed the driver's seat which is where the controller is found. I plugged it back in and what you describe occurred so i unplugged it. It is supposed to be for one touch up function on the driver side window.

No you had the wrong one. The connector you show is for cars without sunroof (plug together for no sunroof) - it skips the sunroof in auto close operations - and may well cause this issue also as you noted (if you didn't have a sunroof you wouldn't care). There is another similar connector with black wires that is the ROW mode for express-up (plug to enable ROW mode).

This module lives under the driver seat - done anything there recently?

Make sure the plug shown is not connected.

I do recommend connecting the ROW mode - this was the functionality as designed for the car (before DOT feature deletes). It enables driver's door only express-up with ignition on. It also provides temporary power without the key to operate windows/sunroof whenever a door is open (great for cleaning the car).

BTW - this functionality only applies to '90+ cars with the window controller relay module - earlier cars are just direct drive from the switches.

Alan,
Thanks for the schooling. I had posted this in the past and I was informed that it had to do with the one touch close on the window but thanks again for the clarification.

tony66

i just worked at the front of the seat-once i unjammed the fore/aft movement all the other features in the seat started working rather than just clicking-will investigate further under the drivers seat-
just a further thought would the connectors you are talking about possibly be under the passenger side seat as my car is uk rhd
its possible somebody has tried to fix the seat functions in the past as the front cover was off the motors etc
will report back if i find anything amiss/joined that shouldnt be

Something else to check: that the window and sunroof switches are the correct variant. If one or more of the switches were replaced with incorrect parts, you can get very strange results.

See this old post that has some details that might be useful. (Details related to window switch; I'm not sure about the changes to the sunroof switch.)

It would be worth verifying that for your '91, both window switches are 928.613.123.07 (and not 928.613.123.05). Likewise, that the sunroof switch is a 928.613.120.02 and not a 928.613.120.00.

You probably have the correct window switches (since you said they're three wire), but I suppose there's a possibility that the brown wire could have been snipped off.


I hope your problem doesn't require as much troubleshooting as the one that Bill Ball dealt with 8 years ago!

Hey Alan, can you elaborate on "connecting the ROW mode" ... there's a 'similar connector with black wires' down there that enables the auto-up function? This is a case where a photo would be nice to see exactly what to look for, where to plug it in, etc.

Alan

Tom - it's pretty easy really. You do have to take the driver's seat out for easy access - it may be possible to do with the seat in place & raised to maximum - but certainly difficult!.

The window module is pretty much in the middle under the seat. There are two connectors - they should be taped up in black cloth tape (similar to the CE looms). See the picture earlier in this thread for how the connector looks. There are two identical connectors that for a USA car with sunroof should both be disconnected. One connector pair has a black wire on each side - this is the one you need to connect together. The other one has a Grey/Blue and a Black/Blue wire - leave this one disconnected (unless you don't have a sunroof).

Done!

To the OP - your UK car should have this black to black connector plugged together already - do check that the Grey/Blue and Black/Blue connector isn't also plugged together - these sound like classic symptoms of that... Did it ever work correctly since you had the car? could someone else have thought it should be connected? - it's not at all obvious - unless you have the seat out...

the previous owner had it 16 years,i have never removed seat[had car 3 months] as yet-until this week it never moved in any direction-it needs bolsters refurbed so will need to come out anyway and then i will investigate and report back

Alan

The main question there was "Did it (windows/sunroof) ever work correctly since you had the car?"

If it worked correctly and then stopped working this obviously can't be the cause - but if it's always been like this since you got it -I'd say it's a fair chance that this is the cause.
