MBC300V6

I have a 2010 C300. My air conditioner will blow non cooled air intermittently. This happens most often after the car has been driven and sits in hot sun say 15 minutes. Seems to happen when outside temperature is over 90 degrees Fahrenheit. Does anyone have a diagnosis or can you give me a clue as to which part is failing so I can change the part out?

Hi and welcome!

I moved your post to this forum, I'm sure other C300 owners will be glad to offer help.

This usually happens when the AC is running low on refrigerant. When is the last time you had an AC service? I usually do that every 2 years. I clean up the system and recharge it using a machine at a shop. Keeps the compressor healthy and going.
