Yes, all of those things are on the same fuse circuit - the key on
circuit, so if there is a ground anywhere in the system, they will all
go on and off simultaneously. It may be that the fuse connection is
starting to be corroded and intermittent, check that first.  I think
it's the bottom or second from the bottom fuse in the 4 fuse block.  I'd
go look but my son is out driving the car now.  I spent many hours
trying to sort out why none of those things worked in my 75 restoration
/ V8 conversion project (of course after the engine was in and running
did I realize the problem).  I have the entire circuit highlighted in my
shop manual, and I had to follow every circuit, test for voltage and
shorts with a multimeter, unplug things one at a time, before finally
determining that my tachometer power wire was hooked up to the spade
connector on the body of the unit instead of the insulated internals
(yes, I did it myself, I must confess - but jeez, it was out of the car
for 7 months and I'm terrible with electricity !!).  Once that was
connected correctly, everything worked. Good luck with the search.

Safety Fast,
