I had this problem as well. It was a short circuit between a gauge illumina=
tion wire connector and the heater control cable, which had become lose. Th=
is control cable is made of metal parts =E2=80=93 the inner and outer cable=
s. This makes, that the cable is attached to ground connections =E2=80=93 b=
eginning on the heater valve on the engine block.

This circuit is unfused regrettably.

So I had to replace a part of the wiring loom in the dashboard.

Nasty job, but it is possible to be done in some hours.

 

Cheers,

Hans

                Headlamps are not fused, nor is the horn.   Blinkers are fu=
sed.

                I would have a good look for any wiring that might have bee=
n disturbed by the engine R&R, though this seems to be a behind-dash situat=
ion unless the cover was removed from the steering column during your work.=
  

                Signal flasher is over passenger=E2=80=99s knees, or right =
side, and I recall that all other connections are in the cramped space ahea=
d of the steering wheel.  

                Arguments are frequent about value of fusing headlamps. Whe=
n I installed relays, I installed circuit breakers for them, and fuses for =
overdrive and fuel pump.  Your fuses will give clues to the search for the =
problem.

anyone have a check here first recommendation or a list of what to check fi=

Thanks!  wiring doesn=E2=80=99t scare me at all; I=E2=80=99m looking forwar=
