The air not blowing out of the vents in a car but actually if you can hear that air is kicking but its not flowing out of the vents, then this can be the reason:--
There are two types of motor mostly seen in car heater box.
- There is a blend
door and motor in the heater box.
- The blend door motor comes on when
you select a setting.
- It actuates the blend door and directs
the flow of air to the proper place.
- One is the motor powered electric automotive current.
- And other is the motor powered by vacuum
in your car any of this motor can be there.
Many times the blend
door gets stuck from debris that falls down through the vents. Also it is
possible that the blend door motor is bad or simply came unplugged. Some of
these motors are powered by electric automotive current and some are powered by
vacuum hoses. It is possible for the vacuum hoses to break or become unplugged.
you will have to check all this options to locate the fault for what is stopping the air from flowing out of the car vents.
this will help.good luck.
