Just bought a 2002 C320 wagon in great condition, low KMs, but with the dreaded battery drain. Drove the car briefly on Sunday. Completely dead on Tuesday. Charged the battery and drove today. Reading through some threads, I suspect one or both seat control modules are draining the battery. I disabled both seats by removing the 3 fuses for each seat. My question is, will that keep power from going through the SCMs? If not, how do I locate and disconnect the SCMs?

 

Pulling the fuses will not stop the seat power drain. You need to disconnect the plugs under the seats.

 

Thanks for the reply. Very helpful. Which wires do I disconnect below? I still want heat to the seats if possible.
