A/C distribution at low vacuum

Have a problem on the XG (efi) that when I'm running up a hill for too long that the vacuum keeping the a/c running through the vents drops to a point where the air circulation switches to demist - the default

I know on my early 70's Cougars there is a small can in the heater control system to retain vacuum in the line.

Is this a common problem or do I have something wrong in the HVAC system? i would suspect it would be common across XE and XF as well?

Re: A/C distribution at low vacuum

Can't help you with a fix, but used to happen with my XF Ghia, especially towing a car trailer up a long grade.....
