I'd love to take a picture and help you but unfortunately Evosportworld won't let us post pictures anymore. I'll be on AIM most of the day so if you see me on there I'll explain it to you then.

ac recharge diagram c36?

AcousticplayerJ · 05-27-2010, 10:55 PM

since I recharged my system with a leak kit, it's been great! I assume I would have seen a leak by now (knock on wood that I won't). The pressure has remained fairly constant. Keep in mind that when you measure the pressure, it will vary depending on the temperature surrounding the port and also if the engine and compressor were just running. When a gas gets compressed enough, it becomes liquid. If that liquid warms up, it goes back to gas (which takes up more space) and the pressure will show an increased reading. Likewise, as the gas gets re-compressed, the pressure reading will be lower. I know this seems kind of counter-intuitive, but if I remember my chemistry, then this is how it goes.

The issue i'm having is when running the AC, it is super cold on the right side vents and almost warm on the left side. I've tried adjusting vents, reset the system but it continues to do this. Any ideas ?

Warm on one side while cold on the other side may be a stuck duo-valve. I just fixed this problem on my daughter's 96 C220 by cleaning the solenoid plungers in the duo-valve. They had crud built up on them causing the one that controls the passenger side heat to stick open. It was only about a 20-minute job.

It controls the flow of hot water from the cooling system through the heater.
It is located in the top-rear engine compartment on the passenger side under the big plastic cover.

Do a search of this or other MB forums for duo valve.
