: No A/C - Does anyone have a service manual?

06-26-11, 12:59 PM
Stock 06, nothing has been touched. A/C works one day, the next it blows hot air. No service message has ever appeared on the DIC. CCP never falls back to AC Off. High side and low side are 140ish, so it's not blocked. Checked all the fuses. Relay is switching power. Pulled the connector to the compressor, and it never receives power in any state of off/on/high/defrost. Engine revs slightly when the AC is switched on, but the clutch never tries to engage, not even for a split second.

If this were a normal car I would pull the low pressure switch off the can and jump it as that is what I'm being led towards, but I can't find one in this car for the life of me. No one has schematics, and none of the parts houses around me have ever even seen one these. Does anyone have a service manual with the troubleshooting checklist, or any idea of what to check next? I have a feeling that I'm going to be paying a dealer $600 to replace a $20 part in the end, so I'm trying to avoid that inevitability.

Thanks for any help.

See attached. (These are for the 2005 V - I do not know how they differ from an 06.)

Thanks for those, but that didn't help much. Seems everything leads down the path to checking BCM codes and data. Looks like EFILive is the only consumer priced product that will do that?

i have the 06 books... not a digital copy, so if you need I can look something specific up for you if you need.

it's strange as it looks like you have checked most all of the stuff out already.... either way PM me if you need something from the 06 manual

The wire to the compressor is broken somewhere in the loom. I have a temporary fix on until I can find where it has failed.

Thanks for the help again.
