I shorted the wires together from the a/c switch (two terminals pointing up) and with the ignition on. The fan did not come on. I do not have 2 fans, just one.

I ran 12 volts off of the battery to the fan and it came on. I also cleaned the connector (wire harness) going to the fan in hopes that it may have something to do with the condenser fan not coming on. The pressure switch was replaced.

Does anyone know if there is a relay or a resistor associated with this fan? It is a 1980 240d.

My manual doesn't show one.
