How are actuators used to control vehicle mode and temperature?
How are actuators used to control vehicle mode and temperature?
The blower motor moves air through the system. Air may be drawn from the outside or we can recirculate the air that is in the vehicle. This is necessary for maximum cooling and greatly reduces the load on the air-conditioning system. When cooling, dehumidifying it and removing heat makes air far more comfortable.
Where is the AC mode selector / actuator located?
If you look up under the dash on the passenger side you will see an actuator behind the center console, but this is for the passenger side temperature control air-mix. The one you need to address (AC Mode actuator) is located directly above the air-mix actuator (picture included shows both).
What kind of motor does a temperature control system use?
Today, most temperature control systems use digital circuits and electronic actuators. The actuator contains a small motor, gears and a feedback circuit to report the current position of the output shaft. Actuators use 12 volt direct current motors and pulse-width modulated stepper-motors.
What to do if your AC mode selector is stuck?
Start on right hand side. Remove the five screws in the shelf area (three on top. two on bottom) and remove shelf. Remove kick panel under the glove box. Pops out. Pull down the rear edge and then pull away. Be gentle.
How is the HVAC action different from the mode?
No heating or cooling taking place. The HVAC action describes the current action. This is different from the mode, because if a device is set to heat, and the target temperature is already achieved, the device will not be actively heating anymore. Device is turned off. Device is heating. Device is cooling. Device is drying.

What should the temperature of my AC be?
Well, there’s not a universal, fixed temperature your AC should always be blowing. The temperature your AC puts out is relative to the temperature you set on your thermostat. So even though there’s no single ideal temperature, you do want a 16°–22° F difference from the supply air and return air.
