2001 CLK320 128000 miles.

When I turn the air on, it blows cold air for about 2 minutes, then the compressor stops turning and it blow regular air.
If I stop the engine and restart, the same events repeat.

I posted this problem about a year ago, and MB Doc suggested a defective evaporator sensor.

Before I take the bottom of the dash apart to test the evaporator sensor, I would appreciate any insights on numbers that could be out of normal range. The evaporator temperature at 200 (?) degrees is extremely suspicious and could well be the culprit. What would it show on a system working properly? Where is terminal 58d ?

Thanks

The diagnostic codes on the climate control show the following:

01 - 103 In-car temperature sensor

03 - 69 Heater core temperature sensor left
04 - 69 Heater core temperature sensor right

05 - 200 Evaporator temperature sensor
06 - 172 ECT sensor
07 - 8 Refrigerant pressure in bar
08 - 100 Refrigerant temperature sensor

09 - 8 Menu for activation
10 - 0.8 Blower control voltage
20 - 0 Control current for auxiliary fan
21 - 7 Engine speed

22 - 0 Vehicle speed
23 - 0 Terminal 58d, corresponds to 99% battery voltage
24 - 14.2 Battery voltage
40 - 8 Software status

41 - 5 Hardware status
42 - 232 Version code 1 number code
43 - 14 Version code 2 number code
