Your main problem with no vent is a air direction motor/solenoid or door broke or binding.

Welcome to Fixya! There is a Fuse Relay Box under the Hood, Look inside this Box and try to find a Relay or Fuse for the A/C Controls. If you can find this Relay, Replace it. I fnot, Check all the Fuses in this Box and the Box inside the Car. If all the Fuses are Good, You may need to take the A/C Unit out of the Dash and Check the Linkages for one that has come loose. This can happen from Time to Time. Let me know what you find! Please Rate My Response! Thanks!

    Check Closely for a Vacuum Hose that has come undone under there.

    See if you can Trace the Hoses from the Firewall to the Doors and Squeeze them as you go. If they are Clogged you might get it unclogged by doing this.

    Try removing the Vacuum line under the Hood from the Connector and Insert a Wire into the Connector Gently to see if you can get it Unplugged. It could have Dust or Dirt inside of the Hoses.

The vents are usually vacuum controlled ... you need to listen under the dash for a vacuum leak. also on the firewall or close to there you will note a cannister about the size of a film container with a some vacuum hoses going to it... sometimes they become blocked or defective... try tapping it first and listen for vacuum leaks there as well

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...

Often a sign of a blend door problem. The blend door or doors are in the heater a/c box behind the dash.

Dash vents will not blow air. Defroster and floor vents blow fine.


Is it a new vehicle? I had a new vehicle that had the same problem. Answer was that the holes weren't punched out of the vent.
