hi gareth
yes the problem was the air con compressor has been used unfilled due to no refrigerant and oil
caused by the pressure sensor leaking
so i thought bypass the drive to the compressor for a while
so the car is still usable
until i can afford a replacement compressor
if left with the compressor still being driven it would have broke up internally
as its the non clutch type so the internals are always driven air con on or off makes no difference
it was making some horrendous clanking noises
about to seize rendering the vehicle undriveable
all the best
