Check you fuses, and the wiring in the trunk, going down to the lock. Look for shorts. Also try disconnecting rear defroster.

Check the wiring going to the driver's door. Everything you mentioned is associated with that door. Including the rear window defogger (heated outside mirror). Hope that helps! Jim
