My Satellite has what appears to be a rear window defroster/blower in it. It's mounted in the center of the rear deck where a center speaker would be. There is a harness (looks factory) that appears to be for it (black and black w/T wires) in the sill to the corner of the dash where it ends in a plug. there is also a spare 2-terminal plug up there (yellow & orange leads from memory) that may have served to power it - not sure. But I haven't found any means of switching it on/off on the car. I'm not all that interested in restoring it to operating condition at this time - just curious how it was controlled and wired if anyone has seen one of these or has one. Haven't really seen anything in the shop manual wiring diagram for it unless I missed it. Possibly it was a dealer installed option or something.
