Does the blend door need to be open or closed for heat?
Hot engine coolant always flows to the heater core when the engine is running. An electronic motor (blend door actuator) rotates a shaft on a door in the heater box to regulate hot much air passes across the heater core. Blend doors are opened and closed with either a vacuum motor or electronic “flat-pack” motor.
Can I manually move my blend door?
The actuator is what needs replacing. The arm/hinge that is moving up and down is just the thing you need to grab with your finger to manually flip the blend door over to the hot temp side.

Why does AC only work on passenger side?
The most common reason is that the AC equipment that cools the air is under the dashboard in the center and right side of the vehicle (because the steering column get’s in the way). So, the air to the driver’s side has to go farther. That allows it to heat a little more.

If it does not move with the adjustments and commands, there is a problem with the blend door actuator and it will need to be replaced.
Why is my AC cold on one side?
Due to the design of dual AC systems, low refrigerant is the leading cause of drastic temperature difference from one side of the dash to the other. In most cases after the proper charge of Freon is in the car, the temp will blow equally as cold like it should on BOTH sides!Dec 27, 2019.
What is the snowflake button in a car?
The snowflake button is one of the most crucial to the air conditioning’s control. Pushing the aircon snowflake symbol engages the air conditioning, and kick-starts the a/c pump which draws heat and moisture out of the air before leaving it cooler than it was before.
