MB Doc or others; A/C compressor problem
 

MB Doc,

You were in the process of assisting me determine why my a/c compressor is not operating normally. Last week the site crashed and I appearantly lost my post. Let me bring yuou up to date.

1. I tried 3 different Klimas. Compressor still did not function.
2. Refrigerant is charged properly. High and low pressures are OK.
3. Wiring klima terminals 5 to 7 turns the compressor on and the air is cold.
4. With engine running and a/c turned on I get battery voltage between klima terminals 5 and 10. I understand this indicates the push button assembly and the low pressure switch is OK.
5. I originally asked how to test the 105/115 sensor. You replyed that I should simply disconnect it. I did. No change.
6. You then suggested that I check the DCV at the klima TD terminal. I believe you indicated the reading should be between 4 and 6 volts.

This is were we stopped. I checked the DCV at the TD terminal and got one reading of 10.47 - 10.6 volts and a second reading of approx. 9.5 volts. I hope this indicates something. Please advise.

Thank you!
