I also have a C230, and I don't have the digital display. My a/c is driving me crazy and costing me all kinds of money.

The compressor is intermittently turning on and off, especially in hot weather, and when I come to stop, such as at a red light. These cars have a variable pressure compressor, and the A/C system is never supposed to turn off. So far I have replaced:

Compressor
Drier
A/C Hi-Low pressure switch
All O-rings
Expansion Valve
Evaporator Temperature Sensor
Condenser

The system is fully charged and holds a vacuum, but the condenser turns on and off. Belt is new and tight and belt tensioner is tight. All parts used were OEM. This is driving me crazy!

Car cools when the compressor is on just fine.

i feel your pain

i also have the same AC problem. when it works it blows ice cold air. it comes off and on at times. also, the air speed is the same on all numbers. 1 blows just as hard as 5 smh. i've had the belts replaced and a new AC compressor and it still acts up!!
