Errant driver's door window malarkey

[Beardy]

Hi there, new kid on the block here. I have a curious situation with my wife's 2.2 diesel D8 Executive.

I've done a search and couldnt find any similar problem, so here goes...

On locking the car (and all the windows are up) using the RF fob, and the SECONDARY LOCKING button is used
(the little one on the fob, not the main one), the driver's door window comes down and cannot be closed until the
car ignition is enabled again . The window does behave somewhat erratically when trying to reset the window,
from fully down, to fully up again. Faulty sensor/switch somewhere ?

This only affects the driver's window, all the others function OK.

Thanks for any advice, in advance...

Another strange fault from Pugland. Someone's bound to say "BSI" real soon but, to clarify, huh???

Is that a 2.2 HDI D9 or what? And the little button on the remote is for unlocking the car, though that still doesn't explain the window... I have a feeling the one-touch control unit has gone nuts, unfortunatly it seems to be part of the window motor itself.

[steve_earwig]

Just a thought: someone hasn't gone and stuffed an after market alarm on it with closers have they?

[Beardy]

A slight error on my part, it's a 2.1 diesel.

steve_earwig, I'm sure the second/smaller button is for the secondary/deadlocking system.
Herewith from the manual:

"The high frequency remote control has two buttons, A & B.
Pressing A once locks or unlocks the the doors and boot. When locking occurs the indicator lights
illuminate for approximately two seconds.

Pressing A then B deadlocks the vehicle.
Deadlocking closes the windows on vehicles fitted with electric windows, front and rear."

I guess just by reading that, I have partially answered my own query...
Is there a sensor that detects the open/closed condition, I'm guessing the deadlocking signal
is getting misread...?

[steve_earwig]

You've lost me now I'm afraid, my 2,1's only got a one button remote

The sensor should be inside the motor, it senses that the motor has stopped spinning so there's no actual switch or anything.

[steve_earwig]

Fishing now, because I don't really know: if you leave the window open does the deadlocking button on the remote shut it ok?

[Beardy]

I'll try that later. That thought had occurred to me too.

I think that the 406 learn where the window closed position is. so its possible yours has got confused and thinks window is closed when its fully open. i'd disconnect the battery for a while and then run the windows up and down a few times. (they may be set procedure for programming the windows but i am not certain)

He said it's a D8 Steve!
On my Exec, after you've locked the car and then press the deadlocking button it closes any windows that are open.
I can only think that the window auto-reverse needs resetting. This has caught me out when it's been pissing with rain; you've got the window cracked open to have a smoke, go to shut the window and it opens all the way down!

I'll quote the manual;

To re-initialise the safety autoreverse function, lower the window and then raise it by pressing the switch until it is complately closed. (The window will rise in stages of 2 inches)
If ice or frost is present the autoreverse can engage; in this case lower the window completely by pressing the switch, then raise the window until it is completely closed; this will restore normal operation.

Actually it's possible that the glass is binding somewhere in the runners; check for any crap in the channels, they may have also gone hard and be full of moss!

Too late to get in on this one

There was a thread that discussed the auto close on the D8s and the lack of it on the D9s, to be replaced with the venting system (opens the windows a bit - remotely!!!).

Hope the fix given by teamster works

[Beardy]

OK, I deliberately left the window open and then used the deadlock feature, and sure enough it closed the window (Hurrah !) and then promptly opened it again (Boo!).

I've tried the fully open, fully close routine to relearn which is which, but when I fully close the window, it
closes completely (without nudging up in 2" stages, per manual) and then opens again.

It looks to me like I will need to replace the motor - if that is the only part which "knows/learns" where the
window position is. May I presume that there isnt another sensor which might require changing ?

BTW - thanks everyone who has offered advice - it's much appreciated.

Try checking the switch connector at the terminal block in the drivers door,could be corrosion on the terminals

[steve_earwig]

He said it's a D8 Steve!

He also said it was a 2.2 with a two button remote.

[steve_earwig]

It's obviously something to do with the anti-pinch fing, Beardy says he tried the reset in his first post but it's always possible that either a dodgy connection or something up with the guides is throwing the reset off . Umm, it's another (daft) question but is that window slower than the rest?

[Beardy]

The window seems to go up/down at the same speed as the others.
I'll check/clean the switch connections tomorrow and if I can get the door card off without
major trauma, I'll take a look at the mechanics of the open/close and see if anything
is obviously wrong.

In every other respect, the car is in near perfect condition, so I'll chase this problem to
resolve it.

Once again, thanks to all that have contributed.
I'll post tomorrow with my findings, if it doesnt bring on a boredom coma for other boarders.
