MBDoc please help, A/C compressor problem
A few weeks ago you were in the process of assisting me determine why my a/c compressor was not operating normallly. Then the site crashed and I appearantly lost my post. Let me bring you 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 teminals 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 are OK. 5. I orginally asked how to test the 105/115 sensor. You replyed that 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 where 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 approximately 9.5 volts. I hope this indicates something. Please advise. Thank you. |
