I found that my rear heated screen remains on all the time even though i turn the engine off. I have to take the fuse out to stop the current discharging the battery.
I have taken the instrument panel out and following the link about by passing the relay have found that my relays and wires do not match the instructions.
I have power at the fuse box, power at the on/off switch near hazard light, power at the heated element at the back.
I have two relays attached to the bulk head, 1x red (changed) 1x brown. from time to time i get a buzzing from behind the dash until i switch on the rear fog light switch ( wether lights on or not )
Any help would help me remain sane.
