If you do not feel any air or if you only feel air coming through the vents on certain settings the problem may lie with the ac s blower motor or the blower motor resistor.
Car air conditioner blower stops.
1 blower fan problem.
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.
The first thing to check if your car air conditioner does not blow cold air is the condenser fan.
Carac not blowing air from vents because of the following.
Start with the fan speed turned to its highest setting.
The air conditioner won t run properly unless your engine is running.
This one s pretty simple.
If your blower motor slows down when accelerating it may have nothing to do with the motor itself.
But behind the dashboard pushing that air through the climate vents is a simple fan called a blower motor.
One motor is used to move a door that switches airflow modes like defrost heat vent etc.
Give attention to the ac evaporator box water drain tube.
If your car has a max ac setting select that option.
A faulty blower fan can make the car ac stopped working suddenly.
One of the first symptoms of a bad or failing ac blower motor relay is a blown ac blower motor relay circuit fuse.
Most vehicles have at least two of these vacuum motors.
Press this button if you have it then spray down this vent to make sure your cleaning fluid is staying in the system.
The number one cause of failure is a leak due to age and wear.
Ac blowing no air at all.
Many vehicle manufacturers use vacuum motors to operate heating ac doors.
The cool air felt from the dash vents is provided by the ac heater blower motor assembly.
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.
Sometimes blower motors and or their resistors will fail and stop pushing both hot and cold air through the vents.
Check the strength of airflow.
If the fan is damaged and does not operate at full power it will not cool down the heat coming from the refrigerant.
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.
The a c system is a complex one that helps to pull warm humid air from the cabin and replace it with cool dry air.
An electronic leak detector is the best way to check for leaks.
