Why wont my vents change in my car?

Common reasons for this to happen: Blown fuse: Like many electrical units in your car, the ventilation system relies on a fuse for overcurrent protection. If the ventilation system’s fuse blows, then the circuit will stop working, and there will be no power for the vents. Bad relay: A bad relay can also be responsible.

Which actuator controls the defrost?

What does the actuator do? The blend door actuator decides whether the air is going to come through the mid-vent, floor vents, and control defrost, and so on.

What are the symptoms of a bad blend door actuator?

If this filter becomes clogged due to lack maintenance it will stop or slow the flow of air exiting the vents. To check this filter locate the filter housing which can be either under the dash on the passenger side or under the hood of the car, near the base of the windshield on the passenger side, remove the cabin air filter and inspect.

Why does my a / C not work in my car?

Check for vacuum leaks first. Sounds like one or more of the Blend Door Actuators are broken, so that when you tell the climate control where to send air, it can’t actually do it. If you have Auto Climate Control, you have two of these (I think it’s 4 if you have manual A/C and Heating).

Why is there no air coming out of my windshield?

If these air intakes become plugged by a piece of paper, cloth or other form of blockage it will slow or stop the airflow. Inspect both external and internal air intakes located at the base of the windshield (external) and at the passenger side foot well (internal).

Why does my car have low air flow?

If this fan motor is starting to fail it will cause the fan motor to run at a lower speed resulting in low air flow. To test this condition an amp meter is needed, connect the meter lead to the power wire of the fan motor.
