Car Air Conditioner Blower Stops

The air conditioner won t run properly unless your engine is running.

Car air conditioner blower stops.

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. If your blower motor slows down when accelerating it may have nothing to do with the motor itself. 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. One motor is used to move a door that switches airflow modes like defrost heat vent etc.

But behind the dashboard pushing that air through the climate vents is a simple fan called a blower motor. If your car has a max ac setting select that option. If the fan is damaged and does not operate at full power it will not cool down the heat coming from the refrigerant. Start with the fan speed turned to its highest setting.

Carac not blowing air from vents because of the following. Most vehicles have at least two of these vacuum motors. 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.

1 blower fan problem. When the car ac is not blowing air from vents it is a sign of a faulty blower fan or air duct blockage. The number one cause of failure is a leak due to age and wear. Many vehicle manufacturers use vacuum motors to operate heating ac doors.

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. One of the first symptoms of a bad or failing ac blower motor relay is a blown ac blower motor relay circuit fuse. Press this button if you have it then spray down this vent to make sure your cleaning fluid is staying in the system. Sometimes blower motors and or their resistors will fail and stop pushing both hot and cold air through the vents.

Give attention to the ac evaporator box water drain tube. Ac blowing no air at all. 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. This one s pretty simple.

The cool air felt from the dash vents is provided by the ac heater blower motor assembly. 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. An electronic leak detector is the best way to check for leaks.
