What does a ac heater blend door actuator do.
Both terms mean the same.
An actuator can go bad in of two ways.
A sure way to move the blend door some systems took more than a little effort to operate.
A blend door actuator controls the temperature and the flow of the air in a car.
As autos had more and more labor saving devices added as standard equipment heater and air conditioning controls could be operated with less effort when automakers started installing blend door actuators.
A blend door actuator is made up of an electric motor that turns a plastic gear set in one direction or another which is connected to an air control door pivot at the final drive of the unit.
An actuator can become faulty if the plastic gear set turns out to be fragile and it breaks.
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.
First the electric motor can burn out rendering the unit non responsive so nothing changes when the temperature or.
