Sharan Electric Window - One Direction Only!

[Guest nettle]

Hi,

 

I have a yr 2000 (newer model) Sharan with an electric window problem. Near side rear window will only go up and not down. ( I know it will go up as have now removed the mechanism). Works freeling in up direction.

 

No click sound at all when the switch is moved for the down direction, either from the drivers switch or the passengers switch. I have searched the forum and tried to work through the more obvious things.

 

Passenger switch is not problem as have swapped over with front one that works OK.

 

Have checked the rear door wiring and loom - every wire shows electrical continuity through from motor to end of loom. Getting voltage to rear door loom - is there anything I can look for at the output to the loom?

 

Does this "one direction" failure ring a bell with anybody? Is there anything else obvious that I should check other than looking for other wiring problems (bit of a nightmare) or trying a replacement drivers side switch unit?

 

Any help would be very much appreciated.

 

Thanks.

I would take the rubber gaiter of the wiring loom as it passes from the body to the door and physically inspect the wiring, most likely one is partially broken and is high resisitance not allowing enough current for the motor to work

Hi, thanks for suggestion. I have already had the gaiter off and cant see anthing wrong with the wiring. No obvious damage anyway. Thats why I tested with the meter, but I will double check tomorrow. Do you think that I would pick up one wire being higher resistance than the others on the meter?

 

If its not this, any other toughts about what to try next?

 

Thanks.

the thing is this is a classic broken wire situation - I have one myself (rear passenger side window up) but global closing sorts it (separate wire), right sort of age -everything so like big_kev says check the wiring again

when you say "global closing", you mean from turning the key in the door? that didnt work for me. However, I do agree it seems like its probably a wiring problem.

 

One other thing I forgot to mention - some time ago (and this window problem happened some time ago) we had a major leak under the passneger side from the rear wash water supply pipe. Garage sorted it out but floor was flooded. Could this have got into anything you think?

 

Thanks.

IIRC the control box used to be under the seat but was moved to the bulkhead before your car was made (beware my memory I only remember my name because people shout it at me all day :lol:)

Forgive my daftness......i know i have a broken wire that means my rear passenger window dont work,...but....in my sleep sozzled brain,...if the window goes one way but not the toher..how can it be a wireing problem??,,could it be some sort of connection probelem in the switch itself?.....Ive had a window that would only go down and not up and it was the switch at fault......but how can it be a broken wire if it will go up and not down?,,surely gotta be a switch problem?

 

ill go wake up now..

brinnnnnng alarm call ! ! !

 

one wire up / one wire down / common and it appears in the case of global opening/closing 2 more wires ..... still could be switch but some wires get constant flexing :lol:

 

Forgive my daftness......

 

maybe

ahhhh...ok.....thanks for that "i love you all equally." :lol:

window does not go down either from switches or from global closing. So I guess that means could be two wires broken (will have to look more carefully).

 

BUT suggests to me that less likely to be the switch - is the switch effectively bipassed on global closing? - would you agree? or is global closing still reliant on the drivers master switch?

 

thanks.

yes and global closing also bypasses the safety feature where if the windoow is tight/jammed the motor stops - global closing will force it shut if at all possible - course it may bea problem with the motor itself !!:lol:

Where all gals fitted with global closure, I thought it was just the ghia,,,,,,,,,,,could you not pull the switch and use a jumper wire in the multi plug,,, just to rule out the switch :lol:
