Hello,

 

My rear screen heating doesn't appear to be working (2006 C2 coupe)

- button illuminates when pressed
- can hear the relay click
- tested for 12v at relay and all good
- fuses fine
- tried measuring for 12v on the heater elements (or what I think are the heater elements) halfway up the c-pillar and got nothing.

 

I can stick my hand into where the rear seatbelt comes out of the c-pillar and feel a wire and connector (which doesn't appear to be loose) but there's no wiggle room to get them out and test for 12v there.

 

When I try and trace the wiring from the relay, it just disappears into that massive loom. Does anyone know if there's another connector, possibly hiding under that big section of carpet (I don't mean the bit over the ECU but the piece behind it)? I also removed the piece of carpet trim ride up against the rear screen but all I can see is the 3rd brake light cable and the connector for the rear wiper (which was deleted by the previous owner).

 

Any advice, pictures / words welcome.

 

Thanks,

Ben

I don't know if this will be helpful but I've attached a wiring diagram.

You'll notice elongated ovals with text, for example, WL REAR. I presume WL means wire loom and REAR means the relative position in the car.
