Vacuum to ....???
Hey fellow Vetties,
Today's topic would be the identity of the pictured unknown vacuum nip. It's located under passenger's footies. It didn't have an attached hose when I purchased this fine Orange Falme '76 last year. Possible clue: Whirling the temp. thumb wheel doesn't seem to make any difference. Though the A/C basically works, there seems to be no significant discernible difference upon spinning the wheel to bi-level and the other options. Plus, the updated R-134 A/C blows a slight, though cool enough, breeze on my left knee even at high fan. I replaced the fan switch hoping that this would improve the blow velocity (it didn't)....Could this absent vacuum attachment possibly explain my wimpy A/C performance? Do any of you Vette Savants know just where the hose was supposed to go?
As always- Many thanks to this forum!!

Could it be a vacuum actuator to open and or close and bypass door in the heater core housing
It looks like the same one I have in my 70 but not sure about your 76.
Look to see what the other side of the actuator hooks up to and that might tell you what it controls.
Hope this helps.
