I recently posted this question about difficult starting of my 91 Vanagon.
One out of 10-15 times the engine would crank about twice as long as normal
before starting.  My mechanic had found that the voltage in the Hall
sending unit was dropping to about .2 volts when this happened but couldn't
figure out why.

Well......, we replaced the Hall sending unit (new) and now the difficult
start  is almost a constant problem.  It either cranks and starts when you
turn the key or you have to crank it once, stop, then do it again - maybe 3
or 4 times before the engine will start.  This isn't doing my new starter
any good I'm sure!  Ignition switch is new too.

So?  Could the new Hall sending unit be faulty?  Would it be the
distributor?  Possibly a computer problem?  Can any of these be tested
without replacing  them?  Should I go to the VW dealer
(Aaaaaaarrghhhhhhhhhhhh)?

Also:  There is one fuse that serves the rear wiper and the rear auxillary
heater.  My rear wiper motor hasn't worked in a while but I keep blowing
this fuse so then the rear heater doesn't come on either.  I replace the
fuse and the heater works it seems until the next time I drive the van and
try it.  Then the fuse is blown again.

THANKS for any advice.  I want to get these things fixed and working before
I sell it ( I posted it for sale earlier this week).
