can you identify this part?
I am trying to figure out what this part is - the pale orange part in this picture with wires attached at each end. It attaches in engine compartment right behind the driver side headlight in my 1987 300E with a small metal bracket (bracket not shown). It is made of some kind of ceramic or something and mine is badly cracked and corroded at one of the connections. Some kind of resistor? I'm thinking this may have something to do with the a/c electrics?

Aux fan resistor!

Thanks. Next question, what is its function exactly? It resists current on the aux. (for a/c use?) fan, why exactly?

It allows current to turn on the aux fan once the engine temp reaches a certian temp. Not sure what temp, but that is the basic function.

It is used to create the low speed fan function. The wiring goes around the resistore when it wants high fan speed.

The aux fan has two circuits
One is high fan and it is triggered by the engine coolant temp sensor. The other is low fan and it is triggered by the a/c high side pressure switch. The low speed is accomplished by having this droppiong resistor in that circuit.
