Just some words of experience or wisdom for you. I have had A/C issues for 1 1/2 to 2 years now. Neither the Porsche dealer or a local indy A/C guy could figure it out. Dealer did a scan and swapped the A/C control unit, I did some servo motor work etc.

My intermittent issues:

1) freon blow off

2) warmer on passenger side

3) Never super cool on the driver side

4) Coolant temperature slightly warmer

I decided to replace the compressor. The indy A/C guy insisted I replace the A/C dryer as well. Upon removing the dryer he found that the dryer failed. Most of the particles in the dryer clogged at the bottom of the dryer and some leaked out into the condensor. They tried blowing out the condensor and put everything back together but I still had the same issues. They felt from that point that the condensor was clogged and not getting an even flow of freon. They replaced the condensor (front bumper and many other parts have to come off).


A/C is ICE COLD, no more freon blow off, cold on passenger side, coolant temperature not showing as hot.
