OK - here's a puzzler that I could use some help to get started.

At idle, all heat controls (def, panel and foot) work fine. I also ran the flap diagnostics and all work as designed. There is plenty of A/C and heat to all vents.

Here's the twist. When it is cold and I am driving/accel, the foot air is GONE. Idle/decel and it's back - 100%, then driving/accel, the foot air is GONE and back and forth. Other flaps do not seem effected.

Seems it's a vacuum issue for sure, but where do I start? Maybe vac checkvalve?

Any/all ideas welcome - thanks, nidge
