Hello,

My 2007 octavia has started having an issue with the passenger side rear door.

 

It does not unlock with the inside door lock button or keys, there is no sound from the lock mechanism from the non working door so it is impossible to open this one door.

 

Also the window on this door will not open or close from using the controls on the door or driver door controls or car keys.
 

It is as if this one door has no power what so ever.

Any advice is greatly appreciated as I’m not very clued up on cars.

 

thank you! 

 

Start by checking the wires between the door and the chassis. When you open the door, there's a rubber-tube containing the wires. Next step would be to remove the door trim, and check the wires there. There's a control unit, which it all connects to, and which then routes it all inside the car. Look for breaks in the wires, or black spots and the like. The easiest would be to get a read on the car with VCDS, which should tell you where to start looking for a fault. There's some references here:

 

 

 

Ty will try that only managed to message two people so far from that list

Hello

 

i have had one of them machines and no error code got put on.

 

ive had a look at the cables and can’t see anything really.  Any other advice?

Hey,

 

Sorry for not getting back to your, I missed your update.

 

Is sounds strange, that the wouldn't be any error codes - no connection to the door should definitely trigger an error.

 

The next step would be removing the door trim, and take a look at the wires inside the door, and see if any of the wires are broken or blackened, and get a measure on the outputs of the control unit as well as the wires. It's quite a bit of work!
