I thought that this might be the problem but I'm still getting vacuum to the control unit. When I set the air flow to locations other than MAX A/C & PNL FLOOR it seems to switch just fine. When on the PNL FLOOR location it will be on that vents and floor and when I accelerate it will switch to the DEFROST. When I have on MAX A/C it will only be on DEFROST. I wondered if it were because of a no vacuum issue but because it is switching to other places there seems to be at least some. My Vacuum Canister seems to be sound.
Could there be some thing wrong with my control panel.
I've heard of using a type (smoker??) to track down vacuum leaks?
