Hi Mike,
Very interesting, things don't usually heal up of there own accord do they. My immediate thought is that we have enjoyed a long hot spell, taking that into account, is it possible that something has dried out?
Time will tell

Heater failure

Re: Heater failure
PS,
Just re- read your magic fix, you say, that as you inserted the new fuse it was accompanied by an audible click from beneath the fuse box. -Another live circuit with the ignition key removed then - Have you any idea what clicked? If you can identify that item Brian may be able to trace the circuitry and give a hint as to where to look if the problem re-occurs

Re: Heater failure
As requested,
The 10amp fuse , top left is designated No.1 and this supplies power to:-
Heater valve
The clutch for the AC compressor
Auxiliary pump for the V8 engine (halfway up and in front of the engine - can't remember what is for as the V6 engines don't have it).
So with that fuse blown not a lot of the climate control would work, a lucky find Mike.

Re: Heater failure
Thanks guys,
That does explain things somewhat.
I believe the aux coolant pump has something to do with keeping the cabin warm for a while if you are sitting in the car with the engine switched and continues to give some measure of warmth until the engine cools down.
Anyway a result of a sorts but wonder how long the fix will last until the fuse blows again possibly.
Great to have your feed back and comments. Another little lesson we have learned.

Re: Heater failure
Mike you may be luck and it was just an old tired fuse that blew, I know how it feels at times!

PS I thought I'd add this in from the free Jaguar technical manuals
'The V8 engine system, as with current
cars, has a water pump to supplement idle water
flow through the heater and this is mounted on
the right-hand side of the cooling pack. The pump
is held in a mounting rubber, which is pushed
over two pillars on the rear of the fan shroud and
held with two screws.'
