Reply To: Webasto 12v Diesel Heater Wiring Question

Thanks Chris, very helpful, I’m guessing based on your second pic that the two wires when connected to the switch are used to disable the heater but leave the fan running, and that probably given that the heater works without these wires connected at all (on mine at least) that the switch position when in the heater position doesn’t actually do anything, hence why there are two wires and not three. Like yours my two wires come out of the same loom, so I suspect that if I joined these together I would get just fan and no heat, I will test with a meter and give it a go and if it works connect back to the switch on the panel.

Cheers

Jason
