Default AC Problem

With the AC on, the driver's side varies between cool and cold. The passenger side is consistently cold. No codes. I think (but am not yet sure) that it improves as the engine heats up.

Ideas?

I have been able to eliminate both engine temperature and length of time the AC is on as affecting the problem.

I've pulled the dashboard and watched things as I changed the temperature setting. I am confident that the actuators and the vacuum devices are working properly.

Is there a damper down at the bottom that cannot be seen from above?

Anyone?

Low freon is a known culprit of cool to warm driver side air been there done that get a set of gauges and check low and high side levels

Also check your vacuum line under the battery to see if it's damaged, etc and that your getting plenty of vacuum on it. When idling, the engine makes plenty of vacuum but when accelerating it drops off. Maybe partially disconnected or pulled loose from the rear of the intake manifold? Won't hurt to check both places.
