AC compressor shuts off at idle

by Tom Pylant
(Fairfax, VA)

I have 2004 Corvette. I recently installed a new torquer v2 cam and heads. My car came with the dual climate control system. At idle the AC compressor shuts off. Once the start driving the AC compressor re-engages at approx. 1,000 RPMs. I have spoken to two builder/tuners about the issue however no one seems to know what the correction may be.

starstarstarstarstar 		Possible bad clutch NEW
by: Funroadahead

While it's possible this behaviour is triggered somehow by the new cam, it is also the way a bad compressor clutch will act. Drives you insane because you only blow cold when you're moving, not at idle when you want it most.
A quick test is to turn it on max while at idle and whack the clutch face with a hammer. If it engages, you've found your culprit.

starstarstarstarstar 		Possible programming issue
by: Chris

I would research to find out what causes AC clutches to disengage on a forum like EFI live. Lots of tuners use their software. Not all builders and tuners see problems like these. My guess is the cam at that RPM is causing knock or misfire events to be triggered above a certain threshold. This would take someone willing to spend time experimenting with some tunes. In my opinion it should be the individual who programmed the car originally for the cam. If I had to guess you have a manual transmission car also. I have seen similar issues with torque converters not locking up at cruise speeds on automatics trans cars. Your tuner must not have that much experience tuning Corvettes.
