a/c problem, 3sge swap a/c Options

[99gt3sge]

well before i swapped my 3s my a/c was working nice but the compressor was making noise, so naturally when i swapped i used the jdm compressor and ever since then i charged the system and now only works when the car is cold or when i'm on the highway. on stop and go it stops working have any of you guys experience this? the only thing I'm guessing that the compressor that i'm using might be for r12 and my car uses 134 since it's a 99.

that's really odd, it may be somekind of a control problem. If you can get a refrigerant manifold and hook up the gages and report what the pressures are doing.

In my case, the gauges read fine.

When I turn it back on, it's as if the compressor never kicked on, but it does because the RPMs drop. The low side pressure stays at around 100 psi when the compressor apparently doesn't kick on.

When it works fine, the pressures are at around 30-35 psi which is perfect.
