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