Both front electric windows stopped working

[Mywindowsarepoo]

I have a Skoda fabia 2007 and both my electric windows have suddenly stopped working. I have checked all fuses l. All fine. I have checked continuity on all wires to switches and motors. All fine. Even done some soldering on the switches to rule them out of the problem. Really starting to grind my gears so if anyone has had this problem or knows how to help please do

Could be the electronic control unit which is integral with the drivers window motor.

Sounds like what TMB has said. It is a majorly common fault, happened to mine also! The problem is sourcing a motor, Skoda dealers ask anywhere from £150-£200 for a new one and sourcing a used one is like looking for a needle in a haystack! You HAVE TO have the right part number, make sure you triple check it's the correct part for your car before buying from any dealer/breaker. Good luck!

Hi, I have a similar problem on my 2006 1.4 petrol Fabia, electric windows in the front only, had intermittent operation, could reset them by removing the connectors in the doors and the fuses etc as suggested in all the other threads on here, but now neither function except if i do the following:

Removed the battery for 2-3 hours (was doing other work)

all wires in the door panels and connectors are OK , no faults

Switches OK

When i reconnected the battery i found out the passenger windows would operate, but fail after a while.

I suspected the drivers door controller/motor may be faulty, I removed all the plugs going into the switches and motor, but the passenger windows did not function.

I again disconnected the battery for 2 hrs, reconnected the battery and the passenger window worked again for a while!, none of the drivers side window controls/motor were connected.

 

I can repeat this by disconnecting the battery, but can do that forever!

 

Anyone had similar fault?, i have read lots of people replace the drivers side motor, but reluctant to do this as the passenger window functions for a while without it!

 

I also read it may be a fault with 'comfort control module' in the drivers side foot well, i believe this controls the cruise control and various other bits, but all those work without problem.

 

Help!

 

I hope i have not hijacked the tread from the OP but may help.

 

TIA

Yes cessnadriver, does indeed sound like the common drivers window motor/module. I had this issue and found that the simplest 'quick fix' is to swap the fuses around, the windows will work until the car is switched off for a short while! I juggle fuses 46, 58, 68. Hope this helps temporarily but you will need to source a new motor/module, after searching for weeks I found one on eBay for £60, double check it's the right part number for your model and year, then check again! They're hard to find! ;)

Thanks for the reply got them to temporarily work by juggling the fuses and looking on a more permanent fix 

[CessnaDriver]

Hi, thanks for the replies, the good old fuse swap and door plug fix no longer work ☹, only the passenger’s window  works if I disconnect the battery for 2hrs, then the passenger window works until I turn the ignition turned off.

 

All this with ALL the driver’s side window motor and controller disconnected.

 

I can’t understand why the passenger side works if the driver’s side electronics control both sides and is not even connected, will keep looking until I find the answer.

 

Whatever happened to simplicity, 10 + wires going into a motor control unit, madness?

[MattT9667]

I had this issue when I bought my 2005 VRS. I checked all the fuses and even replaced them all to make doubly sure and it didn't work. I then triple checked and gave the contacts that the blade fuses fit into a scrape with a watchmakers screwdriver, re-fitted the fuses and they sprung to life. Been fine since and that was about 4 months ago.

 

Might be worth a shot?

UPDATE - Windows now working. - Long story but may help others.

 

After several months of trying all the fixes, found on this and other sites, passenger and drivers side windows now work.

 

The drivers side window motor did not have a fault, all switches and wiring checked 100%. Comfort module OK

 

My car needed a cam belt change, I decided to take it to a Skoda dealer, I know the bloke under the railway arches would have been a fraction of the cost, but thought I would let them take a look as the EPC light was randomly coming on and the engine would stop at junctions/lights etc, the light would come on as soon as the brake peddle was pressed, and the engine could be restarted without a problem.

 

I could reset the EPC light by removing the battery for about an hour, this would also let the passenger window work util the ignition was switched off after the reset, then would only work again if is disconnected the battery again, the drivers side window would not move.

 

I collected the car and all was OK for the first few days, no random EPC light and the windows worked, they had not changed any parts except cam belt related parts, and had reset the error codes and whatever else their fancy diagnostic tools do.

 

A couple of days later I opened the drivers window the engine management and EPC light came on the the engine cut out, i restarted the engine, both lights remained on, as I pressed the window up the engine cut out again, lucky the window had only opened a few mm, every time I operated the window the engine cut out, the passenger window worked OK!

 

I called the dealer and they said to bring it back and the would take a look, after a few days the called and said all now OK, the had road tested it opened and closed the windows with engine on/off, driving, stationary etc and all was good, they had found that a sensor in the throttle body was faulty, it was replaced and all has been OK for 4 weeks now, I use the car for work 5 days a week 80 mile round trip each day of motorway, been opening and closing windows and no problems so far!

 

Never has these problems with my Mk1 Escort, not sure i like modern motoring.

 

Hope this info is useful, This was the first time since 1983 that i have ever taken a car to a main dealer, eye watering prices, but glad its working and all the time I spent has been nearly forgotten!

@CessnaDriver; thanks for the update.

 

Any chance you could phone or drop by that dealership again and ask to chat to the Tech(s) that fixed the car? Say you want to thank them personally or something, to get past the Service desk into 'real work' territory.  I can see how the throttle body fault could be related to the EPC light but can't see any possible link to the window function troubles. It would be really useful to hear what the Tech actually did to fix the window.  

 

Your info about the driver's door module not necessarily being responsible is interesting.

Hi Wino, I have more info and will post this week.

Hello I hope you do not mind me adding to this thread. I no longer have the Monte but my daughter has a 2007 Fabia 1.2. For some time now (months) neither front window would operate. I had tried changing fuses etc and had got the passenger window to work for a short time so I was sure that wiring and motors were ok but could not solve the problem.  When she visited last weekend she got the dreaded EPC warning light en route and found somewhere to stop safely. The AA responded promptly and indicated that both (!) brake lights had failed. Do not know if this was sudden, both together, or if the second failure triggered the fault but they were replaced and he probably reset the error codes. Surprise surprise next day on a trip we found that both windows worked properly. They still worked later that day after the ignition had been switched off but had failed again the next day. It appears to defy logic. Anyone have any further ideas?

I'd put money on a faulty drivers window motor.

[Monte Rob]

Thanks Tech1e but why did that motor work perfectly the other day. It worked totally normally for a few hours.

Because they have a software issue and they are known for being flakey

[Monte Rob]

I am struggling with this. I would have thought that the motor is a hardware issue whereas everything else suggests software - because an error reset seems to have made both motors work for a short while when nothing else was changed. 

[Monte Rob]

I have had a look online and found what may be an answer on a vw forum. https://www.vwt4forum.co.uk/archive/index.php/t-370268.html 

A similar problem appears to have been solved by repairing the motor control module pcb. This involved replacing a relay and capacitor. I am not sure if the unit in the Fabia is the same as this one. Does anyone have any thoughts on this?

Yes, rebooting the control unit will temporarily resolve the issue.

 

We had a technical bulletin on it many moons ago.

Interesting, but not sure why rebooting would change the behaviour if it were a hardware issue? Unless the embedded software has some sort of error counter which locks out function after a while?

 

Can you get a photo of the markings on the relay inside yours? Establishing its availability would be a first step. Capacitor probably easier to find an equivalent and less likely to be the trouble, I'd think.

Edit, if it's the same as the one in that linked post, £4 from Farnell, still available.

Thanks for responses.I won't be able to get a photo for some time as the car is with my daughter 170 miles away, but hopefully the relay is the same as in the vw  (ACT 512) which is easily available). How easy is it to access the window motor and control module?

[Breezy_Pete]

Just door card off, which is reasonably easy, then three (?) screws hold the motor/module onto the door carrier panel.

[Monte Rob]

Thanks Wino. I'll add this to the "to do list" but it may be a while before I get a chance to work on the car again.

[garibaldy]

Our Fabia exhibited this behaviour and I even bought a used motor, however I never got around to fitting it before the windows started working again. In our case the car had some water ingress (you can read about that on one of my previous posts) and i'm convinced that caused the issue with the electric window(s) motor - there are reports on the web about similar scenarios. Does the car have any trapped moisture/signs of condensation if it does then that might be the culprit.

[Monte Rob]

Hi garibaldy, not sure about the water ingress issue but my daughter tells me that windows are working again (2 days in a row). This is clearly after 2 very hot days which could have dried any moisture present, although there was a bad storm on Tuesday night and the car was outside overnight which might cause water ingress. Seems very random. Nothing has been knowingly done that could explain the change to working. I will be keen to continue to monitor developments (from a safe distance).

Hi all,

I have a 2007 Roomster, had it 14 months with no probs. Now the electric windows are not working. (Only two front are electric).

Had a mechanic friend check fuses, switch and check wiring. All fine as far as he could see without taking door card off. Disconnected battery then reconnect and only passenger window worked on passenger side switch. Nothing works on driver's side switch. After reading through various posts, I see it could be anything. Someone told me to buy a relay but the number he gave me Torpan 115664 does not include elec windows when I looked to purchase. Can't afford for it to go to auto-elec as that would probably cost more than car value. Could someone tell me if they think it's more likely to be the switch itself (as I understand wiring inside could be faulty), or a relay or more likely to be the throttle sensor? Or motor, ecu or what?  I am a woman and don't really understand how the electrics work, but I can tell a friend what to try first. Many thanks in advance. Kazz
