disco1 heated rear window problem

Disconnect the wires from the rear window - does it still blow? If so, broken cables in the jumper from the body to door could be the culprit - or the insulation may have chafed through where the cable enters, or runs through, the chassis.

Heated mirrors should come on with the heated rear screen so your short circuit may be in the mirror system. TonyB
thanks for the help. i disconnected the mirror wiring in the footwell and it still blew the fuse. i think the next step will be to check the heater relay.

Are you sure? The Disco II has the mirror heaters associated with the front heated screen. This is all part of the "winter pack" of heated front seats, windscreen and mirrors.
Tony's right - they come on with the rear screen
