Hi, my name is Manny. I’m pretty much still new with owning a Jaguar. I have
1988 XJ40 w/ 148k on it, and so far no real problems. But just recently a
warning message appeared on the computer…saing Circuit 1 failure. Can
anyone give me a clue as to what that might relay to? Thanks in advance.
Circuit 1 failure is a blown fuse in the (i think)passenger side fuse box.

Hi Manny
Be careful about description of Fuse Block locations - depends whether you
are thinking about RHD or LHD!
Certainly for a UK RHD car Circuit 1 Fuse Block is on the RH side (by
driver’s feet - directly under bonnet release catch) whilst Circuit 2 Fuse
Block is in a mirror image position at the LH side (by passenger’s feet).
Circuit 3 Fuse Block is the one inside the centre arm rest/glove box.
The warning messages mean that one or more of the fuses in the Fuse Block
referred to have failed.
Of course, if they keep failing another story starts as to tracking down
what may be wrong (I can give you a list of all the fuse functions if you
need them).

You sure about that? I recently had a Circuit 1 failure, and it was a fuse
in the (UK spec RHD) Passenger side door post fuse location. I thought the
electrics were all the same, LHD or RHD. The only thing I am careful about
is ‘Driver side’ and ‘Passenger side’ on USA cars. I always say ‘RHS
looking forwards’ or whatever.

The one I fixed yesterday was a Circuit 2, and was in the LH
(passenger) footwell. This is as per the handbook (I checked, before
risking checking all the fuses in the wrong box).
BTW it was the aircon LH blower fuse (20A), and it doesn’t seem to
have blown again, so it may have just had a bad day.

Hi Chris
For a moment I thought I was going crackers and couldn’t even copy the
answer correctly from my Jag Service Manuals (proper Jaguar Cars version).
I’ve just been outdoors to the car, switched on and pulled a RH side fuse -
what did I get? ‘Circuit 1 Failure’ !!
Where do we go from here?
