Good morning all. I have a 2004 XK8. I pulled the door panel off the drivers side disconnected the speaker (not working), puddle lamp and connector to the door switch which broke leaving the last two wires exposed. I replaced the speaker that was not working and connected everything back, now the switch for the windows / mirrors / memory do not work. Everything was working correctly prior to disconnecting everything. The door locks work from the remote and windows go down when you open the door and go up when you close them. I have checked the fuses as you indicated which appear fine. I don't want to throw parts at it due to funds. I am not sure what else to look for. Is it possible it is connected to the broken connector to the switch or the switch itself? is there another module in the door that controls things? I spent several hours last night searching but cannot seem to find anything. I did the battery reset and no change. Any thoughts. Any direction as to what to look for would be appreciated.

 

Steve, a few questions to get us started:
Does passenger window switch work?
Key in door, North America = turn key clockwise hold - do all windows open?
Key counterclockwise hold do all windows shut?

Does mirror adjustment work?

Do you have/ can you use a DVM?

John

 

John Thank you for your reply.
Does passenger window switch work? No it does not work since changing the drivers speaker
Key in door, North America = turn key clockwise hold - do all windows open? I only have one key and it does not appear to operate the windows or allow me to unlock the doors.
Key counterclockwise hold do all windows shut? No that does not work

Does mirror adjustment work? No

Do you have/ can you use a DVM? I am not sure what a DVM is please explain.

The remote locks and unlocks the doors. When I open the handle the windows go down like they should and back up when closed. I appreciate any direction you could provide.

 

Ok great feedback. First thought = fuse.

Passenger side fuse#4 5amp door switchpack
Fuse#15 25 amp passenger door switchpack

I'm going to look at something else. Posting this so I don't lose what I typed. Stand by Steve.

Drivers side fuse box:
Fuse #15 25amp drivers door control module

FYI each rear window is separately fused. No fuse listed for other windows

 

Ok making progress.

This is a post that maps the wires for the driver door window / mirror switch pack.

Since I was the author let me whittle it down for you.

We first want to verify power is not present. Take the drivers door switch out. Unplug it.

The switch uses a 20 pin connector. This description uses the following orientation:
Unplug the connector. Hold the connector female pins facing the ceiling, wire harness comes out the back rewards the floor. Rectangular Tab is in 12 o'clock position top center.

PINS:

10. NW. Positive +12volts Power supply

11. OR. LH mirror Vertical (+12volts tilt Up [see pin2]; Ground tilt Down)
12. YO. LH mirror Horizontal (12volts tilt Left [see pin2]; Ground tilt Right)
13. SN. RH mirror Vertical (+12volts tilt Down [see pin2]; Ground tilt Up)
14. YN. RH mirror Horizontal (+12volts tilt Left [see pin2]; Ground tilt Right)
15. Not Used
16. BO. LH Window Up
17. BG. LH Window Down
18. Not Used
19. Not Used
20. BK. Ground (power supply)

Steve grab your voltmeter set to 12volts.one probe in pin 20 (ground), one probe in pin 10 (12volt power for the switch pack) . Turn ignition on.

No voltage? The wire in pin 10 traces back to fuse #4 mentioned above.

Give us feedback partner.

John

 

Thank you John. I will go work on that and get back to you. Thank you for the thorough description extremely helpful.

 

John. I replaced all the 5 amp fuses on the passenger side to be safe. It appears that the # 4 was blown I must have missed that. I was checking the drivers side. The key now locks and windows go down but unable to unlock and have windows go up. For another day. I really appreciate your help. I could not understand what I had done. Thanks again

 

Steve, what a nice message- you made my day!

Don't laugh but after I typed all that it occurred to me, I could have just said fuse #4 :-)

Well let us know when you're ready to trouble shoot the rest.


John

 

You have the best source of info here. Take your time, work thru the problem. You will get thru this. Someone on this forum has had every possible problem.

 

Thanks for all your help got everything back in working order. The only thing that I cannot get to work (not a big deal) is the passenger courtesy light on the door. I have switched the bulb and yes it is plugged in. I have checked all of the fuses and no luck. Any idea where to look?

 

Sounds like it is time to begin tracing the wiring looking for power with a 'VOM' meter. Start at the bulb and work backward. Likely a broken/loose wire connection.

 

Traced it back from the bulb holder to where it enters the door. I do not see any breaks in the wire, does the GRN/W wire go t the door module. Everything else on the passenger side door works, locks, mirrors, windows just the light. I have tried a know good bulb from the drivers side but no luck. Would you suggest pulling the wiring loom from the door and if so how does it disconnect from the door to where it enters the car. Thanks for the help /advice.

 

You should be able to 'probe' the wires as they leave the main body and before entering the door. Use sharp end of positive lead for VOM meter. This should save having to pull wires from door.

 

No don't pull the loom. Are you saying no 12volts at light socket?

Passenger door open car started. Do you get Passenger door open message? If no, door switch problem car doesn't know door is open to turn on lite. Passenger window drops when open door right?

Your year different than mine. Does driver puddle lite turn on when driver door shut, pass door opens? Did you check pass puddle bulb on ohm meter?
Gotta run will check back later 2 - 3 hrs.

John

 

Yes GW goes right into passenger door control module. Other wire is ground

 

Jon thank you for your response.

With car started no passenger door open message, passenger window drops as it should. The drivers side puddle lamp does work and I used the bulb from the drivers side to test as it was a known good bulb. Sounds like the passenger door module. Is that able to be repaired or will I need to source a used one?

Thank you

 

Steve maybe you missed my point, I probably wrote too fast.
Q: if driver door is closed. And you open passenger door, does drivers puddle light lite in sympathy. If yes, it tells me passenger door should reciprocate & that'd eliminate passenger door open closed status issues. WAIT!!!! I SHOULD READ MORE CAREFULLY!!! Ignore everything I said in this paragraph for now!

You just said you do not get a passenger door open red light on dash message! Steve this says the car doesn't think its open! So no, the light shouldn't be on!

Let's lock in the diagnosis:
A. Car running. Passenger door closed. Open driver door - dash red warning lite on message: " Driver door open:
B. Car running driver door closed. Open passenger door: No red lite no warning message on dash!

If A and B are true = faulty passenger door switch. Puddle light is off because door is closed in cars mind.

The other part of previous post was around sympathetic Puddle light illumination status. I'm withdrawing that question for now.

Please just confirm we are in synch. That A and B are true.
If either is false we take a different angle.

Thanks for sticking with me Steve.

For the record: in 1997 & 1998 the door switch status drove dashboard warning message, window drop/raise, Puddle light on /off. At some point a year or 2 later at least one of these 3 dependants was removed from the door switch. I forget which one, but if we are right it looks like that will be window drop. I learned this a yr or 3 ago when trying to help one of us with a 2003 model.

Steve lookin forward to your answer mate!

John.
i appreciate your patience with me.
A and B are correct. No warning when opening passenger door. So Faulty door switch it sounds like. Is the switch repairable or should I source a used one?

Thank you

 

Switch costs about 6 bucks. Getting to it is a bit of a pita, not complicated. Kind of job that'll take 2hrs but save you hundreds. You got a garage? Just do it yourself. My switch fixe itself half way through the job. Plenty of other folks found that a well directed spray of wd40 cleared the problem.

Let's ask others exactly where to squirt the wd40. If that fails I'll look up switch part # so you can buy from Digi Key a huge mail order electronics retailer in USA.

Hey at least you have direction now ! Plus you already know how to pull off the door card.

John

 

I appreciate all of your help. I week definetly wait top tip if WD40 well work and where to already it.
I am willing to do the work as out of money to just buy parts.

Thanks again
