Technical 2010 Multipla Front electric windows problem

[johngreenhalgh]

Hi folks

My Multipla had a fault where the front window switch on the driver's side for the passenger side window had failed, so I replaced it and now both windows won't operate at all, completely dead.

Logically, I suspected it was the fuse, so I looked to change it and to my surprise, the diagram in the handbook bears no relation to the fuse box actually fitted to the car.

However, after some internet searching I discovered that the diagram for the mkI multipla does match my fuse box. So I pulled the 20A fuse I thought was for the electric windows and it's not blown, I tried replacing it anyways, still no life in the windows. So now I'm wondering if I do have the correct info on the fuse box and if I did find the right fuse. I'm stumped.

The fuse I replaced is F3 in the diagram below.

Some of these diagrams are more confusing than helpful. I would have a good look at all the fuses and see if any are blown. There could be a relay involved in the power supply.

I have had this same problem before but cant remember the solution. I think it was a duff switch on the drivers window that caused the passenger window issue so see if you can test both switches to start with.

Thanks for your reply. I have tried the fuses cant find a blown one but there is one I cant get out which would be the likely candidate. At the beginning both front windows worked with their respective switches on the doors but the passenger window would not work with the switch in the drivers door.So got a new switch and fitted it that when the problem started and the windows dont work so I suspected it blew the fuse which according to the book is no18.The fuse box does not seem to be like the diagram and no18 is not obvious.Also no18 is a 30amp fuse but is different to all the rest as it seems to have a cage over it Hense I cant see how to remove it Can anybody tell me how to remove this fuse what the technique is and hope that is the culprit because it is now starting to annoy me especially in this hot weather when you cant open the windows

Could you post a photo?

Here's the photo, hope it helps.

Unhook the edges of cage to lift cage off fuse.......

Zoom in on your photo and you can see edge of cage that hooks over a ramp on the fuse holder......the cage isn't strictly required....my guess is they are there for production purposes

There is a relay plate behind a plastic panel in front of front seat foot wells with the 4 window relays

 

[johngreenhalgh]

Thanks for that info got the fuse out but it hasnt blown so need to delve further I will look under that plate see whats happening there Have to be tomorrow now as the Cumbrian weather has beat me fo today raining cats and dogs

 

[jackwhoo]

Perhaps new switch a problem....try removing it and see if either window responds again?
Have you tried rear widows for function? Shouldn't be connected to non functioning front windows but worth checking

 

[johngreenhalgh]

Rear windows are not electric will be looking at panel in footwell next

 

[johngreenhalgh]

Got the panel off, found green box, removed it and opened it, no relays inside, just electronics, so I am baffled as to where these relays are located.

 

[johngreenhalgh]

Has anybody got a copy of the wiring diagram fo the 2010 Multipla diesel. all a bit confusing

Got the panel off, found green box, removed it and opened it, no relays inside, just electronics, so I am baffled as to where these relays are located.

Inside the green box there appear to be two black boxes that look like pcb mount relays.
I do not know if the green box is related to windows.
Perhaps leave the green box alone for now and go back to basics.

Perhaps remove the new switch you fitted and see if any window switch function is restored?


Sorry I do not have a wiring diagram .

 

[johngreenhalgh]

Getting desperate now cant find the problem with the front electric windows.Tried everything I can think of but no luck has anybody got any more ideas.Its frustrating whe just fitting a new window switch has caused all this trouble

So..
Does the Old switch work as before?

Or is it now DEAD : a new fault

 

[johngreenhalgh]

Originally drivers side had 2 switches one of which operated drivers side window fine the other switch for the passenger window didnt work.The passenger side switch worked th window fine.Fitted a new switch to drivers side for passenger window but it or the other 2switches wont now work no power so looked for the fuse which has not blown So problem now is what where is the source of power that supplies the switches from.Cant loc can get the right wiring diagram Ishould be able to work it out hopefully.Thanks for your interest

 

[jackwhoo]

Have you removed the "new" switch to see if that is the problem?
Are you testing with the ignition on?

So you left the Drivers door window switch in place only replacing the passenger window element?

By the driver They are separate switches entirely .....not twin switches as we are now used to on other vehicles
