What can a bad actuator cause?
A faulty blend door actuator can make your driving unpleasant and uncomfortable. Some of the blend door actuator symptomscan vary from hearing the ticking of noise from your dashboard when you start the car or if the heater in our car is blowing cold or the AC is blowing hot.
Why do I have a problem with my actuator?
It helps control the temperature and air flow within the vehicle. When you have a problem controlling the temperature of the air circulating in your car, or if you can’t stop it from shooting out full blast, there’s a good chance that you have a problem with your actuator. Actuator is basically another word for motor.
How can you tell if your car has a bad blend door actuator?
If the vehicle in question still has heat that is blowing hot, but not reaching the desired cold from the A/C system (or vice versa) it can indicate issues with the heating and cooling directly. In the case of the Air Conditioner, if the coolant is low, you can usually tell. Turn the air conditioner on full blast with the engine cold.
Where is the actuator on a car heater?
Most late-model cars use electric motors (called actuators) to change the air temperature and direction of the airflow by opening and closing flaps in the heater box under the dash.
Why is my car blowing hot air instead of cold air?
If this actuator is faulty, your car might blow hot air out from the vents even if you require cold air. The last cause on this list is a faulty heat controller. If this fails, it may send the wrong signal to the blend door actuator, and this may cause it to blow hot air instead of cold.

When to replace the actuator on a car heater?
If the actuator doesn’t move, it’s probably bad. There’s a chance the mode or blend door actuator may be good but the door or linkage is binding, so check it before you replace the actuator (photo above). If the door binds, take it to a pro for replacement.
What is the function of a blend door actuator?
Number 9 is the blend door actuator. It’s getting to it that’s the problem on most vehicles. This example is a Dodge Ram. A blend door actuator receives input from the climate control system and changes the blend of hot/cold air entering the vehicles cabin.
