Your vacuum regulator is bad sometimes if you move the switch from defrost to fav vents really fast it might work but a new vacuum regulator isn't that expensive and it's easy to fix it's behind the controls for your heater ECt

This is the default position of the air blend when an electronic switch is no longer functioning properly either due to electrical malfunction of the swith or an air vacuum leak that prevents the switch from moving the blend levers to direct the air flow.

First you should check for a cracked plastic tube (stiff small straw diameter or smaller tube for vacuum) in the area near the firewall. You can splice a new section or tape it up good if the crack is very small.

Sounds like you have a vacuum leak to the control head. When you lose vacuum the airflow defaults to defrost. Check the vacuum hoses coming into the car on the passenger side under the dash. Supply vacuum is the black tube. There are five colors. Blue, red, yellow, white, and black.

SOURCE: My front defroster doesn't work

Their is a vacuum actuated valve that redirects the flow of air from the panel to the defrost vents when the defrost is selected. I would check the vacuum line running to the valve while the vehicle is running with the defroster on and check whether or not the line is pulling a vacuum to actuate the valve, if not you obviously have a bad line or vacuum line fitting. If you have suction on the vacuum you will need to check the valve and see that is functioning properly. The valve is usually located under the dash on the passengers side. If you are mechanically inclined i would go to a local auto part store and pick up a repair manual for your car for about $20 as they contain diagrams and info that will save you alot of money.

you have a vacuum loss to the ac control head, the motors that divert air are vacuum operated, if you loose vacuum the system goes to defrost for safety reasons, the vacuum comes from the engine, then goes o a plastic vacuum tank under the hook start there, it is a 3/16 id hose.

the deflecter is not working you were probably using the defroster when it quit working you will have to take the dash out in order to replace it with a new one.

SOURCE: when i turn the air on it doesn't flow from the front vents.

Sounds like the switch or actuator is not operating. Some vehicles have mechanical operators, and some have vacuum actuators. If a vacuum line is loose, it will not actuate.

I would suspect either the fan motor or the switch. But you should also check to make sure the fuse has not blown.
