I am trying to find the fuse for my windshield
I have a 1999 XJ8. Same setup as yours, with very minor differences.
I had the same problem, turned out NOT to be fuse, OR bad relays, OR
wiper motor, OR Body Processor Module. It was simply a loose
connection at the body processor module below the Glovebox. I
Literally jiggled the wires, and it started working again, and has been
ever since. I have the Shop Manual, Technical ability, and Tools
available to test all of the circuits involved, and went forth with
printing out the wiring diagrams, and step by step eliminated each,
until I decided to give the connection a jiggle, JUST BEFORE replacing
the Body Processor Module (which would have been expensive)
Try the jiggle trick. Should be able to access harness just below,
and behind the left of the glovebox. touch around up there, but don't
be a brute, as you MAY break stuff.
Check Fuse under hood, (#22) Should be a 30A fuse
Swap the relays located on the drivers side, just behind the
radiator. One is for Wiper motor run, the other is for wiper motor high
Test 4: Jumper Pin 3 & 5 on the LEFT relay (drivers left) (please
remove relay first). This should turn the wipers on, regardless of
whether or not the computer is telling it to run. If wiper does not
turn on, check fuse, or replace wiper motor.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
