I have a 2010 1.2 TSi Fabia Scout.  A year or so ago the drivers door stopped unlocking with the remote and from then on we've had to manually lock and unlock the car (all the other doors still locked and unlocked remotely, just the drivers door was affected).

 

About two weeks ago the fuse for the central locking blew.  I replaced it and then it blew again a few days later.  I replaced it again.

 

No more fuses have blown but about a week ago the light bulb warning light came on and the right rear tail light was out.  It came back on but then went out again.  Meanwhile, the tailgate release button stopped working intermittently.  There was no sound from the mechanism at all.  Since then it has worked sometimes and not others.  During the last week the following things have happened at least once:

 

- Unlocking the car causes the horn to beep and the hazard warning lights to come on

- Unlocking the car caused all the windows to roll down at the same time

- Putting the car in reverse caused the rear windshield wiper to activate

- The windshield wipers were on all the time the ignition was on with no way to turn them off.

- The engine didn't stop when the ignition was turned off (not 100% sure about these last two since I wasn't driving at the time)

 

Does any of this sound familiar to anyone?

 

 

I just spoke to someone who said that holding down the unlock button on the remote can cause all the windows to go down so it's possible the windows thing isn't related to this issue.

Mk2 Fabias seem to be good at breaking wires wherever they are required to move/bend, such as the door hinge area, and probably where any go into the tailgate, so those areas are probably worth checking out.

That's how it should be IFF the front wipers are on at the time reverse is engaged, I believe.

That's a relief.  My paranoia is turning features into bugs.

Yep check the door wring loom for breaks, Does sound very similar to the Mk2 fabia problems.

I've been doing some research and all the problems seem to be related to things connected to the Convenience Control Unit and/or the J519 Voltage regulator which I understand is located just above the clutch pedal.

 

I'm wondering if it's possible some broken wires at the door hinge could be causing these problems.  It seems like the most likely place for the wires to break but then would it affect things like the ignition and the horn?

The way that modern cars are wired with many things running through a central unit, anything is possible.

 

As already mentioned, tackle the "known possibles" first.

 

Any instant fuse blow, has to be a direct short to ground, so often points to broken wires "somewhere"

 

If the drivers door loom is broken, you could have window, locks, lights, all sorts of issues.
