Guys, I have a 2004 Z06 that the A/C was working fine on. I had to take the headers off to get them repaired so I figured, may as well put an underdrive pulley on while it's down.
Here's the issue: since the install, the A/C is all confused at idle. It can't decide to run or not, I can hear the compressor cycling on and off and the light indiciating the A/C is on/off flickers as the compressor cycles rapidly. When the engine is off idle the A/C is fine.
I'm seeing differing info as to whether the pulley underdrives the A/C, but the most recent info is that it does underdrive the A/C 10%. Clearly, something changed. I did hook up the A/C gauges and pressure is in the range.
I need a remedy. Anyone seen this before?
I did do several searches and didn't see a solution in the threads I found.
Thanks.
