Rear Heated window Problem

[Hulmie]

Currently my Heated Rear window isnt working, i have been told this is a common problem and that the wires split between the roof lining and the boot.

I have found a wire split on the drivers side (Brown Wire) and repaired the connection but still the heated rear window doesnt work.

Is there connections for the heated screen on the passenger side?

Thought someone may have had this probl as i was told it was a common thing.
