[Shotimes] AC Question

[Alan Fanning]

I was gratified to see I had some semblance of AC at last week's convention,
given how poorly the wife does without it. It's like as not to blast out hot
air due to an apparent intermittent blend door problem.

What's bothering me at the moment, though, is what appears to be some
interaction between the AC operating and the engine seemingly running
roughly at highway speeds. Almost a jerky feeling, but very subtle.

The clutch gap seems OK.  Any other ideas what to check?

Thanks,

    Alan
