Hello Everyone, new member and extremely grateful for whatever advice you can offer me on this one.

My front passenger window will only go down from the drivers door switch unit. Press switch down - it goes down. Press switch up - it goes DOWN!

Tried window reset procedures and tried new switch pack off eBay, same fault.

Global down and global up work from remote and window works normally from passenger door switch.

Any advice please?

 

Promise I have tried to set up a signature with the key details in as recommended for new members but as I can't see a signature I am guessing no one else can?

 

Hi Peter,
For some reason you are displaying your vehicle spec twice, you will get there!!

Re your door, have you tried to press lock continually when the window is open?

I am sure you have the windows closing on feature with your keys so this may help?

Ty this, I apologise if you've read it?

Good luck, Stu

 

Thanks Stu, originally from Edinburgh myself, so hello there fellow Scot.

I have tried to retrain the windows as described in these links to no effect.

Not sure what you mean by press lock continually when window is open. If you mean hold the up button up when the window is open then yes I have tried that. The only way to get it up is from the global remote all up from the fob or from the passenger door switch.

Thanks for the thought.

Peter

 

Hi and I hope yer lum is reeking fine?

I understand better now, what you are referring too by global remote is (auto closure: sunroof, windows etc, and locking ALL through the fob, holding lock button) and I take it they are working? just the passenger window doesn't go up with the door switch?

Okay Peter, we'll get there and I'll have another look/search for you.

For what its worth, have you tried a good squirt of WD40 in the door locking area or a smidgeon of dry silicon?

Hang cool, Stu

 

As you have eliminated the Driver's Door Switchpack by substitution, it appears there could be a door harness or Driver Door Module issue.

To troubleshoot this you will need to Fig 14.1 in the XJ 2003.5 Model Year Electrical Guide:



As a new member, you don't have sufficient posts to download PDF's from the forum so I have put this document on my MediaFire account. You can download it (free) by following this link:

It's a 5mB download so could take some time if you have a slow internet connection.

Very good of you, thanks. I'll have a study of it and see what I can learn.

 

Yes passenger window won't go up from drivers door switch, in every other sense it works as it should. WD40 squirted into lock area - no change.

 

Hi Peter

I have the same problem but this time with the nearside rear door , works fine on

the door switch but on the drivers switchpack down is down and up is down . I have

also tried a new switch for e bay with no luck . Did you ever cure the problem ?

Any info would be appreciated

Steve

 

No, but I've tried no more than what has been suggested here and swapping the switch pack. My local dealer are happy for me to buy a new dcm and try that but I am not keen on throwing lots of money at the chance of solving a niggle. Peter

 

Hi Peter


My thoughts exactly , other things need doing before the window and its only a minor


fault , if I do manage to sort it ill let you know


Steve

 

Thanks Steve, I will do likewise.
best wishes

 

I've been having the same issue for some years. Has anyone found a solution to this, or does it require a new DCM?

 

A couple of suggestions to try:

Remove plugs from DDM and re plug a couple of times and look

for traces of corrosion and moisture in that area.

Hard reset the battery leads

 

Hi guys,

I know this post is ancient, but I have the very same problem, but with the offside rear door, rear door switch works as it should, global closing and opening works as it should, drivers door switch pack works as it should, with the exception of the offside rear window which, goes down with a down press, and down with an up press, I have also replaced the drivers door switch pack and the same fault remains. I think that maybe I will swap the rear door switch just as a, "what if", but I really don't see that doing anything.

I have just downloaded the electrical guide that GGG put up, thanks for that, although mine is a 2006 model, but it might lead me somewhere.

Thanks

 

I know its an old thread, but having the same issue and have not seen a solution looking through a bunch of threads. If anyone has figured this out please post a solution. Right side rear window goes down when pushing either up or down on the driver's side master switch, works perfectly up and down from the individual window switch. Seems to be common (have read a few threads with this problem), but haven't seen a solution posted yet.

 

I havn't found a fix for this, I kinda let it be as it wasn't a major issue, It works fine off it's own switch and by use of the global open/close on the key fob. But I would love to know what is causing the issue as it's just a bit of a nag.

 

Thanks for replying. Yea, not a huge deal for me either since its the rear passenger window, but still annoying when I do happen to put it down and then need to reach back to get it up. Hopefully someone has figured this out and will see the thread.

 

That is an interesting issue... the windows on the x350 are nearly old school, the door switches simply connect the "up" or "down" terminal from the window motor to ground to activate them. There's no CAN bus involvement, except for the rear window lockout, and the FEM which can inhibit all window operation when the car is locked. The passenger door switches are simply in parallel with the driver's door switch pack. This would almost have to be a wiring failure to the driver's door, like a short between the up/down wires to the switch. Although I can't say I see how that failure mode would only affect the driver's door operation.

I'll mark up the schematics when I get back to my desktop, there's a few checks you can make to see what's going on.

 

That's what I was looking at, I had an X308 before and had trouble with the boot lock, turned out to be a broken wire in the boot lid harness, pared it back rejoined and all was good, of course there are only a few wires in that part, whereas the drivers door has a shed load, but it does kinda make sense as the driver door is constantly opened and closed which will flex any wiring and the possibility of a break is increased over the other doors
