The air will not flow through the dash vents. The fan is working fine, defrost and lower vents work. For some reason the dash vents stopped letting air flow.

I have a 1975 k5 blazer and it blows cold air it worked fine last year but now it only blows cold air even on the defrost setting what can the problem be and how can I fix it?

A vent flap actuator probably needs to be replaced. It's what moves your vent flaps from heat to A/C or to plain "vent air" when you change settings.

The discussion in the link includes vent flap actuators. Unfortunately, they also include the infamous no low speed fan problem too.

Cannot get any air from dash vents while defrost and floor vents work fine...

Your particular actuator will be a different one than they found.
They're all a absolute pain to get at because they can be well buried in the dash. I would start looking under the dash on the passenger side, that's where most of the air control is. Cannot get any air from dash vents while defrost and floor vents work fine...

I have a 1998 dodge 3500 van. When you turn the air conditioning on it won't let the air come through the vents like it is blocked. It works fine when you have it on fan and defrost

there is vacuum lines that operates door panels in the dash to switch from a/c to defrost i think something came loose or you had something fall throgh vents to stop the door from operating correctly.you need to take the glove box panel out and watch the lever as you switch from defrost to a/c.

AC IS BLOWING THROUGH DEFROST VENTS AND LOWER VENTS NOT CENTER VENTS.

The A/C module placed inside central console has air flaps for air flows guiding against center, lateral, lower, defrost - air vents. Air flaps are acting by electrically motorized mechanisms. Here you must search for damages!

Heating / air conditioning control stuck to front defrost vents

There is a vacuum leak under the hood. Find the vacuum line on the passenger side where it comes through the firewall and follow it to the engine. You system needs vacuum to operate and without it the default setting is on defrost for safety reasons.

1996 honda passport defrost has stopped working

The directional door or actuator thereof is inoperative. This door moves when you choose a vent at the selector, and directs the air to the desired vent(s.) When the actuator goes bad, loses vaccuum, or an electric door motor fails, the air will go to a default position that is usually the defrost. Since you are stuck at the dash vent position, closer inspection at the door itself is required. Could be a stuck door or actuator; or less likely, a faulty controller. Good luck, let me know if you need more info. THanks, TT
