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.
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.
