I believe the fan is controlled by one of the switches at the top front of the OM603. Can anyone tell me which switch, and how to connect or ground or power wires to make the fan run constantly. You can put a jumper across the two wires going to one of the sensors on the receiver-drier. I forget which one goes to the fan and which the KLIMA, but you'll find out soon enough. It works because the electric fan is triggered by a logical OR, either the coolant or the refrigerant gets too hot (or both).

Loren, I have attached selected pages from the Electrical Troubleshooting Manual and the ComponentLocations file. The top center picture of the ComponentLocations excerpt shows the location of R15, the Auxiliary Fan Preresistor. Connecting +12 to one side of the resistor (the one with the Black/White wire, if I read the schematic of the ETM correctly) will cause both auxiliary fans to run continuously at full speed.

Re: [MBZ] 124 300D electric fan control
If the low speed isn't running, either the switch on the receiver/ dryer is bad or the resistor is shot. Pull the two wires with pigtails off and short them together, the fan should run. If not, the resistor is open or the relay is bad. Fan will run any time the ignition is on with the two wires shorted.

Re: [MBZ] 124 300D electric fan control
Well, shorting the two wires from the side of the rec/dryer with the ign on did not make the fan run. I don't have a wire to try the resistor. Is it the ceramic one in front of the ABS? The diagram is very hard to see. Seems like the problem may be FUSE fan or relay. I will check the fusebox in the morning. I just thought of that option. I was figuring a temp switch was bad, but maybe not. On Fri, Aug 3, 2012 at 8:52 PM, Diesel Head 126die...@gmail.com wrote: I am headed out to try that. Any idea where the relay is?
