Ac Blower Fan Not Working Car

The relay board provides voltage to many components of the air conditioner including the fan motor.

Ac blower fan not working car.

Here is how to tell which. Start with the fan speed turned to its highest setting. 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. 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.

If air is not blowing from the vents it is not the problem of the refrigerant recycling system a c and can be attributed to the blower motor or a vent control actuator. A faulty blower fan can make the car ac stopped working suddenly. Checked for battery at the blower when the car is running. Blower still does not work.

Turn the air conditioning on while the car is running. Carac not blowing air from vents because of the following. There is no battery to operate the blower. If your air is blowing cool but not cold the problem could be a clogged filter cooling fan problem radiator trouble or it could simply be that you need to recharge your ac.

Why isn t my air conditioner working. The air conditioner won t run properly unless your engine is running. The blower motor is the component responsible for pushing air through the vents of your vehicle s heating and air conditioning systems. Relay boards are often misdiagnosed.

Before replacing the board make sure you check more commonly defective parts particularly the fan motor capacitor and the fan motor itself. Checked continuity of 40 amp blower fuse. Without it the ac system will not be able to circulate any heated or cooled air. The most common causes of broken air conditioning are leaks or compressor issues.

Rotated all the unmarked relays around in the junction box. Blower still does not work. Next move the fan setting from the highest to the lowest. Rotated all the pdc relays around they have the same id other than abs pump.

Start the engine and turn the air conditioner on. The blower motor relay controls the current used to power the blower motor and is subject to the constant on and off switching.
