09 Passenger with H13 Rear Aux. heat option. The rear heater blower will not turn off. I have to pull fuse 31 under the driver seat or it will run the battery completely down. Any ideas? I've turned the rear controls to cool and fan to off with same outcome, makes no difference.

Anybody got a wiring diagram? Possibly a relay that needs changing?
