Hello dear community, my smart, where the cooler is constantly running… I’m a bit perplexed by what that can be. I don’t have a circuit diagram either. But the fan rotates continuously until you plug it off. So it runs even if the ignition is off. Someone’s an idea? I once disconnected the control unit didn’t bring any success. Safety plugs off the same effect as the fan plugs off. But interesting was that the same fuse is also responsible for the rear window heater which was not on or got warm… I found only one circuit diagram in the net. But no idea how far it can be applicable to the roadster… from 451 his hope on your help and hints. Greetings Solid
