does your lights on buzzer work?

 

[kenno69]

Yeah, you mean when door is open and lights are on?
Btw I've tried another interior light in and it still doesn't work, no power at all to it.

My lights on buzzer hasn't worked since I bought the car. Heard it's quite an expensive fix. Please correct me if I'm wrong, which I actually hope I am. Ha ha.

Sounds like a sensor or switch is not working on the driver door, that would explain why its not going ding-ding-ding at you when door is open with lights on. You might have to take driver door trim off too to see if any wires have broken or anything is unplugged.

I think a lot of the relays can be accessed by removing the small compartment on the drivers side. (I just bought an Ibiza Haynes manula and that is what it says).

BTW fuse 30 in the car owner manual is specified as "free". The Haynes manual says it is for the On Board Power Control Unit (Which I think is just a load of relays - accordong to circuit diagrams). Mine is drwing 0.11Amps when the igntion is off.
