what are your a/c problems? what are the high and low side pressures at
2000 rpms? what is the ambent air temp compared to the output temp? answer
these quetions first if you want help. if you think its an evap. problem
then give me more info. never seen a evap clogged the orfice will clog
before the evap. one time saw the fins on a contruction truck clogged
(evap. core is in the heater box) the pressures will be the most helpful.
