A faulty actuator can cause the blend door to be stuck in one position or another, resulting in an outlet temperature that’s hotter or colder than the desired setting.
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.
Can you drive with a broken blend door actuator?
Can I Drive With A Faulty 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.
How do I know if my blend door actuator is working?
A faint clicking or droning sound underneath the dash is usually a blend door actuator noise. This noise may be obvious when you switch on your vehicle AC system or turn on the climate control dial. Most times, switching the climate control dial can temporarily stop the noise.
What happens when blend door actuator fails? – Related Questions
How do you reset a 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.
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 test if an actuator is working?
To test a linear actuator’s current draw, simply connect a multimeter in series with one of the leads of a powered linear actuator, and watch the amperage reading as you extend/retract the rod. Based on the reading, you can determine a power supply that will be able to handle that current draw.
How do I know if my actuator is working?
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.
In order to prevent equipment failure there are several key components to consider when outfitting your actuator or electric motor with the proper fuse. The first of these components is sizing your fuse for the correct electrical draw so knowing your motor is imperative.
How do you troubleshoot a door actuator?
Door Lock Actuator Troubleshooting
Put on your safety glasses.
Remove the door panel to access the door lock actuator.
Visually inspect the actuator to ensure it’s mounted properly and the linkage is not binding.
Remove the actuator connector.
Set your meter to the 20 volts DC scale.
How often should an actuator be replaced?
Age of Actuator
As mentioned before, you can check this information in the user or service manual, but the majority of manufacturers recommend the actuator is replaced at 10 years.
Where are actuators located?
The AC actuator is located above or below the coil. It can be set to either single speed or variable speed. When it is not working properly, your AC will be ineffective, and your power bills can skyrocket.
How many actuators does a car have?
Typically, vehicles have 3 or 4 actuators. Vehicles with rear controlled HVAC will often have additional actuators to control the auxiliary unit, bringing the total per vehicle to as many as 6.
How much do actuators cost?
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.
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 replace an air door actuator?
The Average Cost to Replace a Blend Door Actuator Is $309-$355, Depending on if You Go to the Mechanic or DIY. This price range is based on national averages for all vehicles and does not factor in taxes, fees, or your particular make and model.
