Came to start my van this morning and the Wipers and Heater Motor
wouldn't work.

Are they on the same fuse?

I can see the fuse panel just to the left of the steering column and
none seem to be blown, is this the correct place?

Does anyone have a diagram of what each of these fuses are for?

Any ideas if it's not the fuse?

I have a 1984 water-cooled camper.

Thanks...Mel
