A/C has a leak. High Pressure is ~300PSI, though the system will not hold R-134a and low side pressure is 0 PSI. Should I suspect a crack in the accumulator? I heard a whistling sound from that area when I attempted to fill the system. Car is 3100 V6 2000 SE.

EDIT: If I move the hose right where it connects to the accumulator, it varies the whistling sound. Don't know if that helps.

I suspect either the accumulator or the Hose line into it from the compressor.

It's been over 90 this week with 90% humidity and I am sweating to death.

Thanks,
