Your previous assistance has been faultless so I'm back for more advice;

This morning I noticed that one of the relays in my '87 Westy was
switching erratically & continuously.
I didn't notice any impact upon the van's behaviour (driving at 65mph
on the freeway), but this doesn't sound 'normal' (is there such a thing
for a Vanagon?). I couldn't figure out which relay was switching (a
little difficult under those driving conditions).
At stationary & idle it doesn't do this (that would be too easy..).
I have the following relays above the fuse array;
top row:       blank  blank   43    blank  53  blank
bottom row: blank    18    blank   19     72   21
(I think it's time for me to figure out what they all do)

Any thoughts on what could be happening?

Thanks,
Mike
'87 Westy
