Fabia Convenience Unit

[Ennine]

A friend of mine has a 2009 fabia that has decided to throw a hissy fit. Driver window went up and down a few times by itself then all the way down and stayed put. At the same time the rear wiper aquired a mind of its own. Having checked the obvious and driver door loom I have wound the window up by hand and pulled the fuses. I suspect it is a problem with the convenience unit. I have yet to pull it out but can anyone tell me if it is coded to the car, if so can anyone point me in the direction for unit repair services. I have had a good trawl through the forum for an answer but haven't found anything relevant. It can stay as it is for the moment given the weather but it will need sorting soon.

...could be corroded terminals, all cross-wiring! Not sure if they are coded but some things are so worth asking perhaps a main dealer, if no replies here. Best of luck.

Thanks for that. I intend to whip the unit out and check it for corrosion and/or water ingress, when it gets a ittle warmer. Don't really want to mess with it at all at the moment but if things get worse I may have to.

I could really do with some input here if anyone can help. Now the weather is a little better I want to take a look at this. The only location for the unit I can find is for a left hooker under the plastic panel, would it be the same place or on the offside for a RHD model and still cant seem to find if the unit would need coding or is a simple replacement, like for like. First things first though, where is it, N/S or O/S ?

its on the drivers side, up behind the relay carrier about the same height as your knee. its good fun to get out.

 

Unit WILL need coding 100% and thats after copying code from the old one, unless you know all the coding for the equipment fitted to the car. (see diagram / arrowed section)

It should have stored a fault "if" its got issues.

 

Did you pull the cable cover / grommet fully back when looking at the drivers door loom ? I would still suspect the door loom

There isn't a convenience unit as such that controls the windows.

 

On a 2009 car you have:

 

Comfort Control Module (central door locking) address 46

 

Central Electrics Control Module (aka Boardnetz) address 09

 

Then each door has its own control unit built into the window motor. If you have a problem I would first look at the door wiring loom (in the rubber bellows) and then look at the window motor.

Thank you both for the input. I would normally have made a bee line for the driver door rubber shroud BUT. the lady who owns the car gave told me that whilst driving the driver window started going up and down by itself then went down and stayed down. at the same time the rear wiper came on.  I made the assumption (right;y or wrongly) that ruled out the driver door loom and was a bus issue.  At the time (november) I could do no more than pull the fuses and wind the window up by hand. I am trying to look for a possible common cause for the two symptoms.  I am no stranger to co-incidence but the two issues happening at exacty the same time seems rather suspect.

Thank you again for anay suggestions as to where to start.
