I had this same problem with my 78. If your have vacuum going to the control panel and the control panel is plugged in correctly to the vacuum hoses, it is either a hose problem or the actuator motor used to open that particular door is no good.
I would get some vacumm tubing and replace that first since it is cheapest. You will have to take apart the dash by removing the radio, the guage cluster and a few other parts. Make sure not to confuse the hoses as each vacuum motor must coincide with a numbered "port" on the control panel. This is a pretty big job, so don't start if you don't have a full day to jack with it. If you replace the hose and it still won't work and the control assembly is hooked up to the correct hoses, try changing the actuator motor. If you need to know which hose goes where on the operating assembly, let me know and I'll put it up. It is nice once it works correctly. I had to replace everything though, including the contrrol assembly.

Hi! jhr1992 You need to get the vacuum system checked. The A/C is controlled by engine vacuum. Make sure the vacuum hoses are connected under the hood expecialy the one feeding through the fire wall to the AC Control. You should not hear any vacuum leak sound from under the dash. Sometimes you need to pull the control and just do some repair or replacement.

My Air Cond. cold Air blows out the feet vents, but not the dash vents...WHY??


You most likely have a vacuum leak not allowing the vacuum operated vent/duct inside your instrument panel to operate. Check all of your rubber vacuum hoses in the engine compartment for leaks, cracks or breaks .

Left Vents blow warm/hot air when calling for cold air


Usually a sign of a faulty blend door under the dash.
The blend doors direct air thru the ac and heater core along with the upper and lower vents.

Cold Air Not Blowing Through Vents


Your last guess is probably the right one. The deflectors/directors are vacuum controlled and you may have vacuum line either broken or disconnected; these aren't fun to find. I would start under the hood and make sure the vacuum reservoir is intact (have seen them cracked) and then start tracing hoses from there.

Blower


I don't know about your 'vette specifically, but many cars use vacuum actuators to control where which vents receive the blower's air. This symptom suggests you have a broken or disconnected vacuum hose.

2001 Suzuki XL-7. Heater blows hot one side, cold the other.


No ductwork [to the lower vents] under the dash. They are part of the heater core / blower housing is integrated (all one piece).

After reviewing shop manual, we suspect that one of the three damper flaps is not positioning correctly; or debris has blocked one side (which makes more sense given the symptoms).

We're waiting for the temperatures to get back in the plus numbers to check out the physical arrangement.

Fully warmed up; blowing hot and cold; Suzuki XL-7


Its just a vent damper plate not operating, it's like a gate which controls the flow of air,,usually they are operated by vacuum, or cables.
Service center time, unless you are handy with your own repairs.
