- Replacing the blend door actuator is actually a fairly simple process, and it should take no more than an hour.
- So the labor will cost you around $75 – $150 depending on labor rates at your local repair shop.
- In general, you can expect the total cost to be no more than $400.
Subsequently, What is the difference between blend door and blend door actuator? The blend door can open and close at various positions to block or allow air passing through the heater core in order to achieve the desired temperature inside of the vehicle. The blend door actuator is typically located closer to the heater core and evaporator than the mode door.
How do I reset my blend door actuator? PRESS and HOLD the DOWN arrow for 10-15 seconds to re-initialize the system. Once complete, the switch should display “027” (Figure 5). Once both sets of control boxes are reset, remove the programable hand switch and install the switch that came with your system.
Yet, Are there 2 blend door actuators? Most vehicles use an electric motor actuator to control the position of the blend door (though, some use a mechanical cable instead). Depending on the system design, there may be just one blend door actuator or multiple blend doors and actuators.
How do I know if my blend door is stuck? 
How many blend door actuators does my car have?
Most vehicles have two blend door actuators, one on the driver side and one on the passenger side. Fortunately, you do not need to remove the dashboard in order to get to them. Some experts recommend that you disconnect the vehicle’s battery to remove and replace the blend door actuators.
How do I test my blend door actuator?
Here’s how. Consult the repair manual to identify which actuators control the defrost-vent-floor “mode door” and the temperature-regulating “blend door.” Then peer under the dash and locate the suspect actuator on the heater box. Have a friend switch between modes or temperatures while you watch the actuator.
Where is the blend door actuator located?
The blend door actuator(s) are typically located on the climate control case behind the dashboard.
Does a blend door actuator need to be calibrated?
Your blend doors should be calibrated, especially after having work done on them.
Why is my car blowing hot air on one side and cold on the other?
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. Even well experienced car mechanics may be surprised to learn that as little as 4 to 8 ounces undercharged of 134A can make such a huge difference.
Is a mode door actuator the same as a blend door actuator?
The blend door actuator is typically located closer to the heater core and evaporator than the mode door. Mode Door Actuator: The mode door actuator controls which vent(s) air blows through. The door on this actuator has two positions: closed and open.
Can an actuator drain battery?
The door lock actuator has a battery drain. The lock rods are pushed up and down by the auto door locks. The battery runs down when the interior lights stay on longer than normal. … It’s a bad actuator if it doesn’t work 100 percent of the time.
Is blend door open or closed for heat?
There are just flaps inside the ducts, called blend doors, operated by vacuum motors, that open and close to allow heat or stop heat from coming through the vents into the passenger compartment.
