Passenger Electric Window

[breen77]

Hi

 

I have a sharan 2005 and the passenger window has stopped working. Thankfully the window is closed.

 

It is making a buzzing noise when I press both drivers and passengers buttons. I thought it may have been the motor but got a second hand window regulator and when connected still makes the same buzz noise.

 

Any one any ideas??

Check the wiring in the rubber boots between door and car. Check all of them including the boot. Start with the driver's door first. Wires have been known to break and short out because of the stress on them. Very common problem.

[breen77]

Will do that just had a new wiring loom installed in the front drivers door about 5 months ago so will not be that one.

 

Would the back doors have an effect on the passenger window?? And the the boot gaiter??

maybe on the back doors, If the boot one hasn't been done its almost guaranteed to have something broken, Logic says it shouldn't be affected by the boot, but all sorts of odd symptoms show up with the boot so its certainly possible and definitely worth looking at

[breen77]

Just checked boot and all door gaiters no breaks visible but noticed one of the back doors was dead locked took a while to get open.

 

Reading the net here and all these issues will have something to do with the leak I have in the drivers footwell!!

 

Any more I ideas with the window issue?? Think I may need a new central locking ECU too!! I hate sharans!!

[BrianH]

The other common point where wires can cause a problem is usually in the passenger footwell - around where the join in the rear wash pipe is (under the side trim next to the door).

 

Is this a UK RHD vehicle?

 

The two issues are probabbly being caused by the same thing - the locking ecu on some models sits under the passenger seat and is at risk of getting flooded from what others have said, the locks and window wiring is closly related as the door locks allow global opening if you hold the key on lock/unlock.

 

Any idea where the water is coming from - is it antifreeze or rainwater or washer bottle water?

Thanks for replying. I had an issue with the rear washer joint in the door trim b4 but solved this by connecting it again and that doesn't even work now but still connected????

 

Yes UK RHD Sharan 2005.

 

Never had any water in the passenger side of the car just still the drivers side. I have ripped out the undercarpet placed towels down but can find the leak anywhere. As I siad in my original post when I got the new drivers side wiring loom fitted the fella who done it removed part of the door seal and I am thinking as this leak only started after that job was done it could be that?? Phone VW who quoted me

Do you have a sun roof?

[BrianH]

If you don't have a sunroof try the scuttle drains at the front. Faq section has details on getting to them they get blocked with leaves. Wash pipe is other side so probably not that. Does the pump run when you pull lever or do you just hear the rear wiper going?

 

[breen77]

No sun roof and I have had the scuttle tray out several times and water is running freely from wheel arches.

 

Yes pump goes as if water running but not spraying out if wiper mechanism.

 

Cud the ECU under the passenger seat be the problem for the window?? I know it's the issue with the central locking because when key is pressed all that locks are drivers door fuel cap and boot all same circuit I am led to believe.

 

Desperate now as car has only 100,000 miles on the clock and still a lot if driving in it yet!!!

[SilverBeast]

I believe there is a junction for the ground wire's that is very badly done near where the rear washer hose joins in the passenger footwell. That had also caused lots of electrical issues. Details are on the forum somewhere.

 

For the rear washer check the boot storage compartment on the passenger side for water as there is another similar joint for the hose roughly behind the top back row seatbelt mounting point that came apart on mine. Also check for water coming out of the bottom of the hatch as it can detatch where it goes onto the wiper motor in there. 

probably easiest to take the hatch trim label off and detatch hose from motor and operate rear washto see if water is getting that far, as it could also be blocked in the motor, or just the nozzle.

[breen77]

Will do that for the the washer thanks.

 

Any ideas about my passenger window issue??

[gregers]

has the pollen filter ever been changed?

 

have you tried using a different switch,

 

update your profile to give us a clue whereabouts you are as someone near you may be able to offer some help,or maybe you could borrow their motor to see if it really isnt a wiring problem?

[breen77]

Not sure about Pollen filter change can that leak??

 

Haven't tried different switch but both drivers and passenger switch don't work just the same buzzing noise when pressed.

[BrianH]

Will do that for the the washer thanks.

I'd start looking around that wash joint area as others have reported finding damage to the wires there which would be likly to cause door issues.

 

Is the scuttle tray back in? (When i left mine out for a few days whilst working on the car it appeared to cause more problems with the water getting inside the car, though i couldn't see how it was managing to get in)

 

The ground point that Silverbeast pointed out would be sensible to look at while your there as this may be the cause of the window issue.

 

Have you rechecked the drivers door - i know you say its got a new loom, but it would be sensible to recheck it anyway rather than assuming its ok.

 

Which bit of the door seal is it? are you talking about the long seal that runs round the door or something else?

 

Is the outer weatherstrip in place? (the one that sits on the outside of the glass)?

Not too sure where the ground point is??

 

Yes scuttle tray back in.

 

Is the joint ur talking about along the door trim front passenger?? No water there just checked.

 

The seal is the one that runs along the main body of the car and the door closes on it.

 

How do I replace the pollen filter or check it?? Can that leak?? How can I check that??

[SilverBeast]

Sorry Faulty memory details are here

 

Wires aren't brown but white/red and it only affects circuits supplied by Fuse 32.  Wiring can be damaged and corroding if there has ever been a leak.

The funny thing is the passenger side footwell is bone dry and never leaked. Would u still advise to check this out??

 

That's the seal on the drivers door I have been talking about the weatherseal wud that allow water to get into car? How much is one of these new approx??

[SilverBeast]

Probably not. I'm not even sure fuse 32 is relevant for windows. I'd be more inclined to recheck the wiring in the door gaiters. Try and check resistance with a multimeter rather than relying on a visual inspection. High resistance will not provide enough current to the motor so it won't be able to provide enough "effort" to operate the window. It could be the window itself is jammed or not running freely.

[BrianH]

Doubtful its the window being stuck as another reg has been tried (i take it this has been plugged in loose rather than put in for testing when saying this?) Wire check as you state above sounds the way to go.

 

If that rear washer isn't working but the pump is running it would be advisable to find where the water is going - the usual failure point is that joint as its only pushed together. assuming the water is acutally getting out of the pump that is! (after all its going somewhere if thats the case, and whereever that place is doesn't appear to be allowing it to escape.)

[SilverBeast]

Rear wash motor can run without pushing water as the impellor can be damaged/sheared. Possibly easier to take the hose off the motor first and ensure it is pushing water.

[breen77]

Thanks for all replies.

 

A further update, checked out all door gaiters plus boot gaiter no breaks in the wires.  Disconnected the Central locking ECU under passenger seat buzzing noise still coming from passenger window when button pressed.

 

Done what SilverBeast said in his last post and water is running out of hose when disconnected from rear wiper motor so the motor must be broke and not pushing water out.

 

What can I try next?  I have a video of  the noise the window makes when I press the button if that would be any use?

[BrianH]

when you tried the extra reg how did you try it (did you swap it or did you just plug it in loose?)

I just tried the reg loose and it give the same buzzing noise when I pressed the button.

The box under the passenger seat is for parking sensors, nothing to do with windows.

 

Have you checked wiring for continuity and voltage with a multimeter.
