I have a 2004 996 carrera with an aircon problem.

Basically the air coming out of the vents is cool but not cold.

I thought this was down to the system needing re gassing so I had this done.

The performance seemed to improve for a short time but is now under performing again.

Also the AC compressor clutch seems to be engaging/disengaging every 15-20 seconds on tickover.

Has anyone had a similar experience or can shed any light on this matter.

Cheers

Mike.

You could have a problem on the aircon clutch, an easy task is to clean it by taking apart the pulley assembly or just wash it by the exterior. I had this same issue on my ML55 leaking oil from steering pump over the aircon clutch but in this case the clutch was not engaging at all!!

      List Mates, I have a 2002 996 c4. When my Air conditioner compressor is activated the volume of air coming out of the vents is decreased dramatically.  It still blows cold but just very very low volume or amount. I have had it recharged , checked leaks , replaced condensors etc but nothing changes. As soon as you switch the ac off ( snowflake button) the volume of air through the vents goes right back up.  Volume of air is fine on heat , defrost etc.  I have never had this issue with any other vehicle. Any ideas as to what the problem may be?

      has anyone ever recharged their AC? I have a 2005 Cayenne Turbo. I noticed the other day the AC is not as cold as it used to be. Has anyone used AC Pro to recharge their AC? I believe the refrigerant is the same as what Porsche uses. Is this something that a novice can attempt, or will this damage the AC system by using an after market refrigerant that is not from Porsche?

      Yes I'm back with another problem. Ctt 06 with 4 zone climate control, 45 degrees in dubai and the AC starts to blow hot. Had new gas 1050 grams as per spec after the head gaskets were done 4 months ago, vac test showed no leaks then. 
      I had to keep turning it off and on to get it to kick back in which is suspiciously like the compressor clutch not kicking in. 
      So questions: 
      Possibilities of the cause of intermitted fault?
      Can compressor be repaired if removed? 
       
      Will be swapping the relay later from the rear defogger (same part number 40a relay) to make sure it not that and yes a trip to the local shop for gas volume check and leak test. 
       
      Ruling out the control flaps as when I increase temp to 29 it is blowing super hot and all the control flaps and noises can be heard switching, and back to low setting gives hot air but much less roasting.

      Let me start by saying I'm not a mechanic, so I do not know the names of certain parts.  This is of a 2004 Porsche Cayenne Turbo w/ 4-Zone Climate
       
      However, what I do know is, the A/C electric motor (955.624.915.01) under passenger side dash is steadily going back and forth regardless of A/C or Heat On/Off, High Low, Dash,Floor, Etc.  It connects to a flap on the passenger side firewall.  Pictures are of the same part, just different angles.
       
      My question is this.  How do I test this electric motor to determine if it is bad?  Or could something else be bad causing the motor to constantly move?  Any response will be appreciated.
