Hello fellow C300 owners-My 2012 A/C does not seem to be working right. I just had the freon charged up and there are no leaks. The air on the driver side is sort of cold, the passenger side iswarm-ish. At "max a/c" the temp of the air is not cold. Can someone tell me what might be the problem. Thanks!!

 

How exactly did you charge up that “Freon”?

 

i didn't change the freon, i added to it. I did not do it personally, the mechanic who works on my cars did

 

Did the problem exist before you had the system charged?
It could be a blend door problem.
Why not take it back to the mechanic who did the charge?

 

the problem started about 3 months ago. my mechanic is not well versed on diagnosing Mercedes air conditioning problems. my research on this issue comes up with "blend door problem" also. I may have to take it to an indy Merc shop.

 

An independent shop specializing in MB sounds like a good idea.

 

mare you sure it’s not leaking? My c250 is a 12 and I had a leaking hose. My mechanic told me they made a revised part even. Also make sure mechanic used one of the machines to charge it and not some Freon charge can from the auto store.
