Heated rear window... advice?

[Torroni]

My heated rear window has stopped working!

Switch, relay and fuse are ok. The back window is making a circuit so the problem must lie in the wire which runs from the front to the back of the car.

Has anyone got advice on how I can access this wire to either repair, replace or route a new cable in somewhere? I'm not sure where it starts at the front of the car?

It should run with the rest of the loom and up the c-piller. Take off the sill trim and have a look for the wire.

Where is the sill trim... do you mean the bit of plastic at the bottom of the door?

[Pistol Pete]

Yes. The wire will run front to back. Trace the wire from the screen or from the fuse board and try and locate a break in it.

[Torroni]

Ok I'll have to try and find it.. although I'm guessing access is going to be a problem and probably not much chance of puling another cable all the way through?

[AlexW]

You could do, but once you remove the sill trim and rear door cards it should be easy enough to track it, but get some insulation tape to wrap up the loom after. You could just put a new wire in from where ever you pick it up from each end and tape that to the loom.

Test the wire to the elements is going 12v when you switch it on
