If the system is low on freon the a/c compressor will cycle on and off in short intervals. The compressor is located at the lower driver's side section of the engine. The center of the pulley will move and stop as it cycles. You should be able to hear it cycling also. Since it is an older model car you will probably have to use R12 refrigerant which is not available at most autoparts stores. A qualified technician should be able to recharge your a/c but the problem will most likely persist because of a leak somewhere, either in the lines or the condenser/evaporator.

Look to see if the compressor is running when the ac is on. If not, then check the Freon pressure, as the compressor won't run if the Freon is low.

The compressor may have a leak, to check you would need freon with UV dye and a light kit to check for a leak in the a/c system. * If it is leaking - replacement or possible sealing The compressor may not be cycling on due to low freon levels. * Recharge a/c system Those are the most common issues.
Where do you add freon to your 95 Honda Accord air conditioner compressor?
There will be two couplers on the system. The one you add freon to is the larger one on the low pressure line. From your compressor, there are two lines, the low pressure is the larger one. Check it and you will find a coupler between the compressor and the firewall.

Mabe your compressor is not kicking on for some reason. Check to see if the front of your compressor starts spinning when you turn it on. If it don't check to see if there is power to the wires that go to your compressor. If there is power you have a bad compressor. If there is not check the fuses or relays.

If you got to any auto parts store, they will have bottles of r134a that you can buy that have gauges in the handles that will tell you when you have enough in it. If you system wont cool or is out of freon you have a leak and should get it check to have a repair done, an ac system with out freon has no lub either and that will lead to compressor burn out. The freon cools the air and lubs the compressor.

Low or no freon will cause the AC not to work. Also if the clutch on the AC compressor has failed, or if the compressor itself failed.
