A/C Mercedes E320 weird problem

The A/C went out on this 2000 Mercedes drivers side first, and then two weeks later on the passenger side. This seems strange to me. The system has pressure and won’t allow any more freon to be added. What is going on? A friend suggested that it could be the expander valve. I have no idea.

The problem is not with the AC system itself, but with the air distribution system within the car.

Take the car to an automotive AC specialist and prepare to write a large check.

It’s highly unlikely you will fix this yourself.

Good luck.
