Question Air conditioning lost?

Post heads/cam install, the AC stopped working. No visible crimped/bent lines, and a recharge of the system holds pressure. When commanded by a scan tool to turn on, the compressor runs and the AC functions correctly, nice and cool.

So what's the next step? Most likely culprit(s)? Any way that LS1edit tuning might have messed up the PCM somehow to provoke this problem?


Thanks in advance for any ideas.

There is a %TPS to enable and disable the compressor in edit. It is something you could look at.

We need a separate topic on the Board to cover AC issues!
