Haven't been able to find a new blower motor resistor that is confirmed to work for the Fiero. If anyone has one to sell me or can point me towards a new one I would appreciate it. Need it soon as it is getting cold out and need defrost.
Someone correct me if I'm wrong, but I believe you can run the fan on high speed without the ballast resistor. Only the lower 3 speeds run through the coils on the resistor. This should work for you until you can find a replacement.
