No power to radio,clock, outside mirrors or interior lights(cab). Other interrior lights ok. Checked fuses and wiring to fuse box, all ok. The fuse that covers mirrors, clock, radio and cab lights is ok. Why can’t I get any power to it?
Did you check the fuses visually or with a meter?
I would find a set of wiring diagrams for the van - you might be able to get them via Autozone’s online repair manuals (http://www.autozone.com - you need to set up a a login - easy, nonintrusive).
Then I’d start tracing tracing the circuits via the diagram to start looking for the most likely places to start with actual inspection. But I’m not an expert either - I just happened across this with no responses and thought I’d at least point you to the website.
