Problems with air conditioner.

My car is a 2000 GT with 57000 on the odometer, and i rarely ever use the air conditioner. When i do turn on the a/c the compressor seems to cycle every 4-6 seconds and when coasting to a stop in neutral the RPMs like to dip to around 500 and fluctuate, any help from yall on this issue? Thanks for all replies.

If your a/c cycles that fast, then you are low on freon. This could also be the cause of your rpm fluctuation. Have the a/c charged and see what happens. If it still fluctuates, it may be the compressor going bad. Engine may be struggling to turn the drive pulley on the compressor.

The idle problem could be caused by a faulty Idle Air Control valve.
