The bus has two seperate motors for the wipers. Of course they stopped working So,..what did I do ? I ripped them out and checked inside and sure enough,...wires were fried. Ok 42 years of labor,...gone! Is it possible to get a modern day system for this bus that will be seperate electrical hook ups for each wiper,...or do I go with the one for the one motor for two wipers system and plug them holes?..lol. Going deep deep on this ol gal....everything restorified baby !!...lol. Thanx guys! Cheerz !
