Car Air Conditioner Blower Motor Not Working

Restore multiple speeds to your auto heater air conditioner blower by replacing a resistor module.

Car air conditioner blower motor not working.

One of the first symptoms of a bad or failing ac blower motor relay is a blown ac blower motor relay circuit fuse. Hopefully the blower motor simply blew a fuse. Sometimes blower motors and or their resistors will fail and stop pushing both hot and cold air through the vents. The air conditioner won t run properly unless your engine is running.

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 acâ s blower motor or the blower motor resistor. They do this for cooling purposes. Start the engine and turn the air conditioner on. Car heater blowing cold air.

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. It s a simple quick change out. When the car ac is not blowing air from vents it is a sign of a faulty blower fan or air duct blockage. Start with the fan speed turned to its highest setting.

Here is how to tell which. Most ac systems are designed to work within a large range of temperature variants and environments however due to numerous causes the air conditioner is still prone to overheating. So a problem with the vehicle s cooling system might also cause the heater to underperform or stop working. They mount the resister block in the air conditioner or heater case because of the generous amounts of air flow.

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. These blower motor resistors get hot. Swap in the new part and reinstall the screws and connector. A faulty blower fan can make the car ac stopped working suddenly.

Carac not blowing air from vents because of the following. Turn the air conditioning on while the car is running. 1 blower fan problem. Another common problem with the air conditioner blower motor not starting up is caused by overheating.

Next move the fan setting from the highest to the lowest. Low coolant level counterintuitively the same system that keeps your engine cool is responsible for the heater working. The problem sounds like it is with your blower motor not your ac system. That s why they re not far from the squirrel cage itself.

Depending on what kind of car you have it should be a pretty simple fix. Check the strength of airflow. Thanks for your question about your ac. Remove the electrical connector retaining screws and the old resistor module.

Find your fuse panel and check the fuse for the blower motor or vent fan or something like that.
