    well yesterday i had a auto electrician( one that clearly hates LR) out to diagnose the a/c fault,
    the guy was chasing wires back and fourth through the dash/into engine bay

    2 hrs later he finds a burnt out resistor that runs between ecu and the pressure swich,

    i also had him wire my driving lights
    total cost $363.00

    now i have ice cold ac just in time for summer

    Glenn he didn't say what value the resistor is? I think mine's gone too.

    a/c fixed

    Thanks... I got it working this arvo - bad connection somewhere near the a/c thermostat (behind the centre vents). I had disconnected most of the relays driver & passenger side and cycled through replacing them using a couple of new ones.
    There was no earth getting to the compressor relay (drivers side behind the kick panel) in, we were checking the wiring near the thermostat and it came good. Wiggled all the wires but it wouldn't fault again.

    The thing I thought was a resistor (encased in red plastic, on the right side near the fuse panel) wasn't a resistor at all, it's a 1uF capacitor (not labelled, had to measure it with a C meter). Nothing to do with the a/c I think & not in the diagram in the Haynes manual.

    So all good for now or until next time I go over a big bump anyway.

    YES! Mine caught fire and short of taking it to an autoelectrician I still can't work out how to fix it.

    But........It also used to have a constant bad overheating problem which has since been fixed, previous owner stuck an EA Ford fan on it & it was blowing the wrong way. Apparently they are all right for v-belt type systems but not serpentine.
    So was thinking/wondering if this overheating might be the problem
    oh it is a 96 3.9L auto V8
