I tested the fans at the receiver-dryer by connecting the two leads. Both fans came on. It is a '91 300E, is this normal?
The top of the engine test ... I found the connector for the temp gauge. I disconnected it and verified that is what is was. There is another two wire connector close to it. Is this a thermo sensor for the fans? I pulled the connector and bridged the two but it didn't seem to do anything.
