For some reason this summer, my 79 Vette is having problems switching from the vent setting to the heater or defogger settings. I have to play with the slider a couple of times before it goes where I need it it. Is it a vacuum problem or a mechanical one?

Thanks

Do you hear the blend door moving when you switch to the different settings? Do you hear a whistling sound under the dash indicating a vacuum leak?

I get a Hiss sometimes all the vents work but sometimes it seems that there is a delay, so I have to play around with levers.
