Better check the actuator motors that control the temperature to the vents, and the system that controls the actuators. This will require special equipment to communicate with the climate control computer, so it's best to take this to a Mercedes shop to get this looked at, here are some in your area: http://repairpal.com/directory?address=38018&car_brand_na...

1999 e320 ac frion was low 2 cans took care of it the person i fixed it for is very happy now he can go golf on saturday without being hot , it was a cheap fix

Sounds like the same thing I'm dealing with. The solution is likely to evac and recharge, and also check first for worn hoses and loose connections in the a/c system.
