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.

check the resistor, and check expansion valve, that happened to mine after the swap. but i barely used my ac b4 swap im still using 5s compressor, i didnt wanna use 3s compressor because i believed it uses a different resistor or something. thats y i just stuck with the oem 5s comp. i have a spare 5s compressor if u wanna try it Neal
