Suggestion

If I do see 12V at the input connector for the clutch, disconnect the connector to the clutch and use an Ohmmeter to read the resistance of the clutch coil.

Suggestion

If it's open (more likely) it will read the same as when the probes aren't connected to anything (some very high number, which is basically the internal resistance of the meter being used.)

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1Original post

Hello, I have a 2006 Cayman S and my AC is not blowing cold air. I have checked the fuse and relay (both are good). I believe the compressor is not running. Icarsoft shows error code C144, 8001, P0645. Can someone provide some advise on the cause of this issue. Any help will be appreciate. Thank you.

POST 3Original post

I copied Don’s ******** response since it’s super helpful (and relevant to my 06 Boxster whose AC isn’t working either). ———————————————————— I notice the two bottom screen captures show that there are additional pages of info available (ie 1/2, 1/4) it might be interesting to know what that info is. Since you have a 987.1 your AC does have a clutch. The clutch is opened/closed by a relay in response to the cooling ECU . Questions I would have are: 1. Can I hear the relay open/close? 2. If not - does it work if I replace the relay? 3. If it does make a click for open/close - do I have 12.6V at the input side of the switched terminals ( voltmeter needed)? 4. If it does make a click - do I see 12V at the output terminal of the relay? 5. If #4 is true - do I see 12V at the input connector for the clutch? 6. If I do see 12V at the input connector for the clutch, disconnect the connector to the clutch and use an Ohmmeter to read the resistance of the clutch coil. If its "infinity" (0.0) then the clutch coil is likely kaput. That can be changed without removing the compressor or venting the system to air. That's the start for diagnostics. I'd also check if the system had gas in it (a refrigeration gauge connected to the high/low side ports. Lack of gas can cause prevent the system from working since there is a safety switch that shuts the system down if there isn't any refrigerant in it.

I did have a Freon fully charged last week at a shop. I will start looking into the possible cause above. Thank you.

POST 5Original post

I should correct one thing - when measuring the continuity of the clutch coil, if it's shorted it will read 0.0 Ohms. If it's open (more likely) it will read the same as when the probes aren't connected to anything (some very high number, which is basically the internal resistance of the meter being used.) I guess I should correct this on ******** (easy since I'm a mod there.. )
