I have been having problems for 2 years with my 1996 850glt the
compressor will run all the time and overheat then just shut down.  I
took it to volvo and first they told me evaporator coil then once it
was there they told me compressor too,  well the car is not leaking
freon because its been doing this for 2 years,  I dont think its the
evap coil and I dont want to pay the 2500 bucks for the whole system,
finally I called volvo and told them I only want the compressor and
clutch replaced, im having that done today,  I need input if im doing
the right thing,  I did take to a foreign car garage for 2end opinion
they said evap too.  if it is evap shoulnt it be leaking freon?  I had
pressure test done and no leaks were found.  always blows cold.  kelly
