2004 Mercedes SClass Air Conditioner Not Working Properly
Hello
I have a 2004 Mercedes SClass Base model. My air conditioner seems to work off and on. Sometimes when I first start the car it runs fine and cools the car. Other times the left side only throws cool air while the right blows warm air. Sometimes it just blows warm air throughout. I took it to get the lines checked for leaks and freon levels and all is fine. I also checked the AC compressor and it seems to work fine as well. I did replace the blower with another blower from the dealer because it previously burnt out during the winter. When it does blow cold air the rear passenger vents barely release enough to cool off anyone sitting in the back.
I have been reading about some DUO VALVE but have absolutely no idea where it is or any DIY steps to fix the problem.
I did run the AC hidden codes and no error code appears.. (Just ERROR ----)
PLEASE any help would be greatly appreciated!! Thanks!!!!

look on this forum for replacement , but its the car under the hood and under the wiper blades, and also try youtube for video, it shold solve the problem.
