Long time lurker here. I have a 1990 Vanagon, its not  a camper and no ac. My radiator fan is not working. When I jump the fan with the plug that attaches to the radiator fan switch, the R/Bk wire makes the fan work and the R/Bl wire blows #1 fuse. I have replaced the Radiator fan. In the Bentley schematics and in my vehicle
I don’t see a Low speed radiator fan resistor. I do see a second stage radiator cooling relay. Could a bad relay cause a fuse to blow? Thanks.
