AC started blowing warm air. I thought I just needed a Freon charge. When I went to add Freon the Compressor clutch would engage then disengage every 5 to 10 seconds. Any idea on what would cause the clutch to keep cycling like this. I have replaced the control unit behind the glove box once before the controller for the blower fan speed. Would that have anything to do with the compressor clutch? Any help is greatly appreciated. |

No. How many lbs of freon did you add? Did you check the pressure on the low and high side? What were the pressures? |

If you do not have the correct amount of R134A in the system it will not function right.The only way to get the proper amount of R134A in the system is with the correct tools which are not cheap.Just take it to a shop to have the A/C system properly tested for leaks and operation. |

Finally, someone that agrees with me that the recharge kits are garbage. if the clutch was cycling, it is obviously needs some refrigerant. take it to a shop and they will nitrogen leak check the system and then draw a vacuum on the system. just a quick visual for you is to look for any oil spots on the hoses, around the compressor, anywhere on the condenser or on the gauge access. what ever you do DON'T use the recharge kit. bring it to me and i will do it for a 6 pack |

Mine blew warm air for about a year, and it get hot here, I finally went to an a/c guy. I had a $28.00 clutch switch that was bad cost me $103 to bleed the system , buy and install the new switch, and recharge the system. |

Now that I think about it, if you ran the A/C a lot when that part was bad it could of harmed the compressor. I would think the high pressure switch would kick it off but theres a possibility something was damaged. |

Not sure if you ever got this figured out but I had the same problema several months back. Ended up buying a used compressor for $85 and swapped it out. Solved my problem immediately. Turned out the magnetic clutch assembly or somethin to that effect had been stripped and was slipping. Hope all works out for you. |
