When to know if your air door actuator is bad?
If the fan works on high speed only, then you know that you have a bad resistor. You will want to make sure that the connector hasn’t burnt out as well.
How to test for noise under your dash as an air door actuator?
You will be testing for voltage at each of the input wires. In this example, you will get a full 12V at each wire when that speed is selected from the controller if the controller is working. Test the BRN wire first on the lowest speed. Move to the TAN wire and the next speed setting on the controller.
How does a full speed air door actuator work?
For every speed step up, the power signal goes through one less resistor inside the unit, thus supplying more voltage to the fan motor to turn it faster. Notice that full speed bypasses the resistor all together and triggers the relay to supply full 12V to the fan motor.
What are visual instructions for air door actuator replacement?
VISUAL INSTRUCTIONS/DIRECTIONS DIY: Do it yourself, simple, easy and straight to the point, first person point of view visual instructions on “How to “/”Show You” replacing and installing car parts, diagnosing, preventative maintenance. Used Car Automotive Technician at Toyota Dealership SO SAVE YOUR $$!!

What to do if your actuator makes a flapping noise?
MAKE ABSOLUTELY CERTAIN YOU DON’T CONFUSE THE OLD AND NEW ACTUATORS. Putting the old on back on would suck. Once you re-attach the wiring, proceed to reassemble the dash as indicated in the dash removal instructions.Follow the precautions to make sure the airbags don’t explode, turn on the car and verify that the flapping noise is gone.

What does the actuator on a jeep do?
The actuator is responsible for moving the air direction and temperature doors inside the heater plenum; their job is to manage mode settings like re-circulation modes, mid vent, defrost and fresh air, floor as well as temperature. Also, they control the cold and hot settings for left and right passenger sections.
How does an air blend door actuator work?
An air blend door actuator is constructed from a plastic housing, a small electric motor and a plastic gear set. A door position sensor is also incorporate into the unit to send feed back information to the climate control computer.
How can I tell if my blend door actuator is faulty?
This simple diagnosis can help you determine if your blend door actuator is faulty. The blend door is the problem if the air is cooler than in vent position.The problem is in the cooling system if you have to turn the temp knob at a cold position to feel the A/C.
Where is the air door actuator under the dash?
Most vehicles, this is located directly under the passenger side dash or behind the glove box. If the fan works on high speed only, then you know that you have a bad resistor. You will want to make sure that the connector hasn’t burnt out as well. Replace resistor and connector as needed.
