The fans that blow for heat or defrost aren't working. In addition the antenna won't operate. Two seemingly unrelated problems maybe. I have checked the fuses and the connections on the fuse block. Fuses are fine and the connections are clean with no corrosion. The fuse for the heater fan I think is labelled Ventil RAL. The antenna circuit has the interior light and hazard light both which work. I am more interested in the heater fan fix as I never listen to the radio. But it would be nice to fix the antenna issue at some point. I am at a loss as to what to look for next. 77 308.
