Sometimes blower motors and or their resistors will fail and stop pushing both hot and cold air through the vents.
Car air conditioner blower stops.
The air conditioner won t run properly unless your engine is running.
Give attention to the ac evaporator box water drain tube.
1 blower fan problem.
If the blower motor relay develops any sort of problem that hinders its ability to properly limit and distribute power it may cause the blower motor fuse to blow.
Most vehicles have at least two of these vacuum motors.
The number one cause of failure is a leak due to age and wear.
But behind the dashboard pushing that air through the climate vents is a simple fan called a blower motor.
An electronic leak detector is the best way to check for leaks.
The cool air felt from the dash vents is provided by the ac heater blower motor assembly.
If your blower motor slows down when accelerating it may have nothing to do with the motor itself.
Carac not blowing air from vents because of the following.
Many vehicle manufacturers use vacuum motors to operate heating ac doors.
The little button with arrows pointing a circle tells your car to stop taking air from the outside and instead recycle the air from the inside.
Press this button if you have it then spray down this vent to make sure your cleaning fluid is staying in the system.
One of the first symptoms of a bad or failing ac blower motor relay is a blown ac blower motor relay circuit fuse.
The best setting for diagnosis is fresh air not recirculated with the air blowing out of the center vents in the dash and the ac turned on.

Ac blowing no air at all.

One motor is used to move a door that switches airflow modes like defrost heat vent etc.
If your car has a max ac setting select that option.
Check the strength of airflow.
The blower motor resistor or blower module gets hot as it powers the fan so often times they can burn out causing certain speeds of the fan in your car to stop working the fan can be stuck on one speed only work on high speed or not work on any settings.
