Can I ask whilst we are on the subject of Frankia/Mercedes.
To the right of the Eberspacher Booster Heater switch on the dash, there is a large red indicator lamp. When I start the engine, it illuminates (briefly) and I hear a click from the rear habiation systems.
I have a problem on my 2008 sprinter base motorhome. I have no power to fan/heater/ac controls on dashboard. I have checked all fuses, from the chart that have any reference to fans or heating and have not found any defective. Does anyone know if there is a relay or fuse that I may have missed.[/b]
