Busted vacuum line to the temperature control unit, the "flap" that moves the air to different positions is controlled by vacuum pressure. You might also replace the switch.

Air does not blow through vent on 1994 chevy silverado


Which vents, floor--defrost--dash? Can you hear the blower motor running? The squirrel cage could have broken loose from blower motor? There could be an actuator problem under the dash? If actuators are vacuum controlled and vacuum is lost, it might default to defrost, only blow out defrost vents.

Heater blows air thru floor vents and dash vents but no air thru defrost windshield vent


Suspect a defective blend door actuator motor that controls airflow for the defrost. This electric motor may be defective and in some makes and models can be extremely difficult/expensive laborwise to replace

Air blows out thru the vents but just no hot air, aslo i have to hit the dash for the air to come out thru the dash vents at times.


sounds like bad acuator motor, this is what moves the door in heater box to set hot or cold air, and other motors to set air to blow thru defrost, vent or floor. good luck.

Air blend doors do not work. Air blows from defroster vents


check or loss of vacuum to mode control switch in dash ac control. these are not blend doors, they are air flow control, a blend door controls the air temperature not where it comes out.

A/C blows from defrost and floor vents, nothing from dash vents.


the switch where you turn it to blowing at your head is probably out. you will need to replace the switch control where your defrost, foot, head etc. what make, model, year is your vehicle?

1994 Grand Prix Air blows thru defrost and feet, not middle vents


I've had the same problem with my 1994 Grand Am. It was a vacuum leak (the controls for the vents operate by using vacuum). My battery leaks acid on the components below (still does--not sure why). There is a vacuum line that runs below the battery and when the acid builds up on the line, it eats a hole in it. I have fixed it a couple times (by inserting a thin plastic tube into the rubber hose at the break). Still can't figure out the battery acid problem, but I've got the vacuum line problem solved. I only have to repair it about every 3 or 4 years. Not sure if your problem is the same, but it could be. Just remove the air filter housing from the choke cover, and possibly you might need to remove your battery as well. You can see the vacuum lines easily then. They come from different directions and go into a bulbous shaped device in that area (not sure what that is--this last time I did the repair, I bypassed it entirely by connecting the line coming from the firewall area directly to the line going into the engine around the choke). Hope that helps!

Air will not blow out of panel vents


vents are blocked so air is diverted to other vents, check and clean if necessary
