Windows 101

Seems to be a fairly common occurrence on here atm and funnily enough has just happened to me. My passenger window wasn't dropping automatically on opening and wasn't responding to the reset procedure detailed in the manual, despite multiple attempts - so I thought I'd post my (successful) findings here for posterity and perhaps it will help. I really should have taken some pictures but I got too excited what with playing with screw drivers and stuff. Obviously at your own risk etc. Be super careful playing with pointy tools and leather. You need hex/allen and torx heads.

I figured I needed to try a 'hard' reset of the window module after reading a bit on here and finally after some further advice from Bridge Mill.

As I see it 2 options are available to depower said unit (well 3 but I wasn't inclined to disconnect the battery)

A) remove the fuse in the passenger fusebox hidden under the carpet and located under the slopping bit of the passenger footwell (might be 81 or 82 if remember correctly?). Involves lifting the carpet and undoing a number of bolts.
or
B) remove door trim to access module directly. Probably the best option as it gives the opportunity to check for loose wiring also

I went with 'B'

Pretty straight forward with the workshop manual. It's possible to get away without removing the door card and by lifting the bottom of the door card outwards but as I hadn't seen it before I did it anyway for better access

so...

Start with handle
- Two very obvious hex bolts in the handle. remove.
- there's a small red plug behind the handle which will probably fall out at this point. pick up and forget to put back in later...
- pull the handle towards you - comes straight out with door pull attached to the door.
- On the back of handle is a bit of leather trim which just pulls away on mine.
- Looking at the back of the unit you can disconnect the door pull cable at this point (just gently twists to remove)
- Two small hex bolts now allow removal the door pull cable from trim piece completely

Onto the door card
- lower window completely
- six screws to remove
- one torx screw upper front
- one torx in the round air vent middle front
- four torx along bottom of door
- lift card out and upward and off it comes. It may be a little stiff - there are three sort of contact points at the top of the door which it fits very snugly over.
- there are several multiplugs on the back, unplug them all and put the door card down. In the event I just disconnected the window switch and it gave me enough flexibility with my helper to get in there without snagging or pulling on anything.
- Window module is at the lower front part of the door
- Disconnect plugs. I removed just the two grey plugs (one either end) and left the lower black connected. This seemed to be enough to remove power. Plugs were very stiff to remove, the larger rear one in particular even with the release tab pushed in so take care.
- wait a few secs
- Reconnect, hunt around for all those screws and put everything back together in reverse

Once power is connected there was a more 'purposeful' click from the door.

- Do the door reset procedure again. I ran it up and down a few times also.

job done

Excellent information, my passenger window needs a frequent reset which does work for it.
Do you think if you put it into a dealer they would automatically replace the module in the door when a hard reset is only required?
Could you not also do a hard reset via the battery disconnect switch?

DM,
Excellent information and detail. Hope that works for everyone.
One thing you missed though, was a step by step pictorial.
Great technical information.

Bookmarked for when mine does it!

Cheers for putting the time into it DM

I went for option A, it was fuse 82. Actually to get to fuse 82 it is easier if you remove the bigger connector to the bottom left of the fuse box, which seemed to remove power to the fuse box which fixed the problem without removing the fuse.

I had a flat battery a couple of weeks back and the drivers side window wouldn't drop on opening unlike the passenger side which is fine. I have tried the button based window reset and waited for the click each time. Failed.

So today I removed the door cards and pulled all three of the plugs from the door module. Failed. Twice.

Anyone with any ideas would be much appreciated as it was fine prior to my flat battery!

Yes option A in the OP is different to what you have tried and easy enough.

Removing the fuse is not going to do anything that unplugging the module (twice) is not going to accomplish other than waste more of the ops time.
The window modules are a known weak point.
I'm informed (by Mike, a helpful gent in Warwickshire) that AM have somewhat acknowledged this and rather than fleecing you for a pair of door modules have revised them such that you can now install them one by one and at a reduced cost.
Op, take it to a dealer/independent or chance your arm sourcing the part and replacing yourself.

Fair point.

Thanks for the advice gents. Much appreciated. Happy to change them myself but do they need coding? And any thoughts why changing my battery would cause this to happen?
