A/C Problem
i just got a 95 Dx hatchback. i turn on the A/C and all i get is hot air. i check the fuses and they are all good. the condenser fan runs but the compressor clutch is not turning i check it by moving it with my hand and it does turn smoothly. Can anyone help thanks.

Re: A/C Problem
If refrigerant pressure on the high side is too high or low, the A/C pressure switch in the receiver/dryer will prevent the compressor clutch from engaging.
When you push the A/C button on, does the engine idle speed increase?
If you switch the compressor clutch relay and condenser fan relay, does the condenser fan now fail to run but the compressor clutch now engages?

Re: A/C Problem
If the idle speed bumps up when the A/C button is pushed, it tells you that the ECU receives the "on" signal from the heater control panel and that the A/C pressure switch is closed (=good). This means that the possibilities are a bad clutch relay, a bad thermal protector on the compressor, or a bad or improperly gapped compressor clutch. The results of swapping the relays should begin to limit the field further.

Re: A/C Problem
Yes it has but it looks like it had low pressure.
