Anybody know of any obvious places to look? It'll blow the fuse, if I put one in, but everything else, including all the other lights seem to work. I took it apart once after being assured by the goof behind the counter at an auto parts place that nobody in the world has difficulty getting the knob off the wiper switch and there is no tool made anywhere to do the job.
Unfortunately, I didn't find any problems when I got the dash apart, but I was worn down after fighting with the knob (made a hook out of a coat hanger) and put it back together. Should have left the wiper knob off. I've been staying home at night, since I can't see the speedometer.
The only non-original item I've found is the radio (I'm at least the third owner), so I'll look at that next time I get it apart.
Thanks!
