:rant: The heater blower on my 1996 164 Lusso only works if the front fogs are on (which means also the headlights). Local professional (supposedly) auto sparky did not have the foggiest (forgive pun). Anyone any ideas? Does it sound like control panel printed circuit fault, or module fault, or is there a real live gremlin in the electrics?? Very elusive problem that's driving me up the wall!
