just picked up a 97 sc2 with non working ac. checked the pressures with my gauges and the low side was 35psi high side was not getting over 130ish, ambient temp 95. clutch is kicking on fine. my mechanic looked at it and hooked it up to his machine and said it had a full charge, told me to replace the expansion valve. did that, charged it up and still have the same problem. tried a junkyard compressor too but the readings are still the same.
what could be causing the high side to stay so low?
