Why is AC not coming out of vent?
The most common cause of low air flow through the vents in your home is blocked or dirty AC filters. When you clean or change your AC filters, be sure to vacuum the metal grates closing the filters in at the same time. Another way to prevent common home cooling problems is to clean your AC registers on a regular basis.
How do I unclog my AC vents?
Here’s What To Do
- Turn off the power connected to the heating and air conditioning system.
- Unscrew the air duct covers or grilles from the walls. Use your brush to clean the grates thoroughly.
- Vacuum the ducts as much as possible. Consider renting a heavy duty vacuum for this purpose.
- Clean the grilles in your ceiling.
Why does my air conditioning stop blowing when I accelerate?
Typically this occurs due to a bad vacuum check valve under the hood. During hard acceleration the AC door system loses vacuum, causing the doors to default to the windshield. This check valve keeps this from occurring.

Why do air vents need to be replaced?

This actuator controls defrost, middle and lower air vents. When it fails it can do so in the defrost position and must be replaced.
Why are the air vents on my car stuck?
This can happens due to a surge or spike in the cars electrical system. Before going too far with any repairs it can be a good idea to remove the climate control fuse and allow the system to power down. When the fuse is reinserted it will allow the system to reset and regain its logic and start working again.
