1.2 Fabia Comfort 09 - electrical issues

[adamyt]

Hiya, I've got a 59 plate Fabia mk2, there's a few electrical issues on it, it's got a severe case of the sads...

 

Here's the symptoms

 

• Electric windows don't work with interior buttons but does when using key
• Numberplate light & cabin lights (the dome works) not working

 

Fuse 16 had popped so I replaced it with another one, switched the lights on and the drivers door card was smoking & the passenger window was moving up and down. I've seen it mentioned that the harnesses to the door tend to fray and cause connection issues. I unplugged the doors harness, replaced the fuse & no fire but also no rear number plate light :/

 

Next steps

 

• Remove door card and check harness
• Identify smoking component - Note: central locking & window still function, speaker?
• Isolate smoking component and replace.
• Repair harness if required.

 

Has anybody seen this? It's not really a major deal because I can wire the tail lights to the brake cluster but it'd be nice to get it all working.

the problem to me is within the door wiring loom...

 

Smoking = direct short to ground as does fuse blowing.

 

Where is the rubber boot from the door wiring loom ?

Yeah fair enough, I'll get the door card out and have a look.

 

I ripped the boot while trying to take it off

Looks like the brown and white+blue cable were shorting in the window switch. Cabin lights now function, will order a new switch and probe out the connector to determine where the fault lies. Harness from what I can see is basically flawless.

 

Only issue is tail lights not illuminating.

 

Correction for original post, the fuse is 36, not 15.

Fuse 17 for numberplate lights (also left side light and left tail light).

Ding ding ding, winner. This sorted it. Tail lights now on. Not sure why the left side lights didn't get flagged in the MOT, saying that I missed it too...

 

Last job is to get a new plug and switch for the electric windows. Hopefully she'll be right.

 

will update when I get around to doing it.

Don't forget to repair/replace the rubber bellows for the a-pillar wiring.  Water will go in there and cause lots of problems without one.
