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.
One of the most common signs of a blend door problem is when the defrost is turned on, but it takes a while to get going. Most of the time, the windshield won’t defrost, does so slowly, or remains foggy after a while.
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 much does it cost to get blend door actuator fixed?
The Best in Auto Repair
The average cost for HVAC blend door actuator replacement is between $322 and $373. Labor costs are estimated between $193 and $243 while parts are priced at $130. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.
How do I reset my blend actuator? – Related Questions
What happens if I don’t fix my blend door actuator?
Technically, you can continue to drive safely with a broken or faulty blend door actuator, but we wouldn’t recommend doing it for long periods of time. The blend door actuator doesn’t affect how your car drives as it is purely a feature of comfort inside the main cabin.
Can a blend door actuator affect the AC?
The most common symptom of the A/C Actuator going bad or when the Blend Door is stuck is when you feel inconsistent air flow coming in. The desired air you want whether it be hot or cold, is being diverted incorrectly, so you are not getting a consistent temperature out of the A/C system.
How do I know if I need a new blend door actuator?
If you find that your car’s temperature is inconsistent or is alternately blowing hot and cold air without you turning the dial, then you may need a new blend door actuator. Unpredictable flow of air: Not only should the temperature of the air stay the same, but it should also come out of the specified vents too.
Mode Door Actuators: The mode door actuator controls what vents have air flow, i.e. floor, panel or front, defrost, or any combination of those. Recirculation Door Actuators: The recirculation door actuator controls the intake of air into the system, either bringing outside air in or using inside air in recirculation.
How do I test a blend door actuator?
Is an actuator expensive to replace?
Luckily, this repair isn’t too expensive or complicated! The average car actuator replacement cost is $300, depending, of course, upon your car’s make and model. In most cases, a mechanic will remove the malfunctioning actuator and replace it with a functioning one.
How do I know if I need a new blend door actuator?
If you find that your car’s temperature is inconsistent or is alternately blowing hot and cold air without you turning the dial, then you may need a new blend door actuator. Unpredictable flow of air: Not only should the temperature of the air stay the same, but it should also come out of the specified vents too.
What causes a door actuator to fail?
There are several factors that can cause a door lock actuator to fail. One is corrosion. Over time, moisture, oil, dust, and debris can enter the actuator or the mechanical links.
How do you know if your actuator is broken?
Symptoms of a Bad or Failing Door Lock Actuator
Unusual noises coming from inside the door.
Power door locks behave erratically.
Power door locks do not function.
What actuator controls the vents?
Mode Door Actuators: The mode door actuator controls what vents have air flow, i.e. floor, panel or front, defrost, or any combination of those. Recirculation Door Actuators: The recirculation door actuator controls the intake of air into the system, either bringing outside air in or using inside air in recirculation.
Does the blend door need to be open or closed for heat?
If replacing a blend door actuator, check to make sure the blend door position is completely closed before installing the new blend door actuator. If the blend door is left open, even slightly, the temperature inside the vehicle will not match the A/C temperature selected.
How do I test my blend door actuator?
To confirm that you’re replacing the right blend door actuator and to test door operation, turn the blower and work the blend door in both directions.You should feel a temperature from the dashboard air vent.
How do I know if my actuator is working?
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.
Does blend door actuator control heat?
A blend door actuator controls the temperature and the flow of the air in a car. If your vehicle is only releasing cold air, or if you are not able to change the airflow, it may be because of a malfunctioning actuator.
What causes blend door actuator to click?
This clicking noise is the result of a failed door actuator; more specifically, it is because the teeth on the plastic gear inside have sheared and are now slipping. Nearly all of these failures have been traced back to using an aftermarket door actuator in the vehicle.
