My friend just bought the 300SE and the radiator fan wiring has been disconnected and it is necessary to connect a temporary wire to the battery. The engine runs fine but other wires under the hood are running here and there... so I need the schmatics that cover wiring under the hood... Maybe a couple bad relays caused the previous owner to rewire in a temporary manner. Thanks for any help forthcoming.....Jim

The climate control system controls the fan(s). There are two relays in the back of the fuse box on the right. The left one controls the regular speed through the engine temp sensor to the climate control system and the right side relay is controlled by the pressure switch on the receiver/dryer. The pressure switch is the top one with the long leads. The relay operates the fan through the large resistor under the brake master cylinder for lower speed operation. There is one fuse, or two, I can't remember right now.

You can test the low speed fan operation by disconnecting the wires at the pressure switch, connecting the leads together and turning the key on. The fan should start. Check for blown fuses, a cracked resistor or seized fan.

How bizarre... yeah, sounds like something was on the fritz.
