First thing you should do is to visit a legit aircon shop. Get the readings from the high side and low side. If you are experiencing high pressure, even when the aux fan is on, it may need replacement na. If not, then maybe your compressor is no longer efficient. When you rev the engine, does the aircon get colder?
