I know its a brushed motor. Can it be re-brushed, rebuilt, etc? If not, who knows what motor can replace it without going to Webasto themselves. All I know is that it has to be a 4500rpm motor. Mine is 12v.
I am not having troubles, just planning for them. :)
Webasto are all highly rebuildable...for a price.
The parts are considered expensive in some circles.
Depending on your circumstances and time available, you may seek out alternative sources of supply, or just order from your local dealer as you need bits and pieces.
Many busnuts have reported that the favorite online classifieds and/or auction sites will yield good results with some patience.
happy coaching!
