Rear Defroster on 200TQW

[Karleen Oosterwal <karleen@jannon.com>]

Listers,

A few weeks ago a lister posted the identical problem I have with my
1990 200TQW.  I apologize if I somehow missed the answer, but I was
unable to find it anywhere.  He asked about the connection/relationship
between the antenna booster and the rear window defogger.  My fuses test
all OK, the switch to the rear defogger works, but nothing works (i.e.
poor radio reception, no defrosting on side mirrors nor rear window).
Could a shorted out rear lighter have anything to do with this? Thanks
for any advise!
