Well, I took my 560sel in to the mechanic today and he was generally impressed with the over-all shape of the car. He said the A/C compressor looked pretty new and that when he went to vacuum out the system, it had barely anything left in it. He recharged it up with new r134a and took it for a drive. Everything was working fine when he pulled back up to the shop. The system was clicking on and off, the compressor had a healthy whirring sound to it and the aux fan was cycling between low and high. Interior was pretty damn cold, I’d say. There’s just one weird thing. When I have the temp wheel set to 22 and the big middle button pressed, the a/c air flow will alternate between blowing out the center vents or the defrost. I don’t remember that being normal on a 300E I used to have a while back. I know from receipts that all of the pods were replaced in 2010, which was 10k miles ago. If I rotate the temp wheel to 18, it’ll ramp up the fan speed and defrost will switch back to center vents. It’s maybe 72 here today. Any thoughts? Vacuum valve sticky or maybe a general vacuum leak vs a pod?
