They do this for cooling purposes.
Car air conditioner blower motor not working.
Start the engine and turn the air conditioner on.
It s a simple quick change out.
Nevertheless often when this component fails it suffers catastrophic heat damage.
Restore multiple speeds to your auto heater air conditioner blower by replacing a resistor module.
One of the first symptoms of a bad or failing ac blower motor relay is a blown ac blower motor relay circuit fuse.
Next move the fan setting from the highest to the lowest.
When the car ac is not blowing air from vents it is a sign of a faulty blower fan or air duct blockage.
The problem sounds like it is with your blower motor not your ac system.
Sometimes blower motors and or their resistors will fail and stop pushing both hot and cold air through the vents.
Most car manufacturers use a.
Start with the fan speed turned to its highest setting.
Car heater blowing cold air.
Check the strength of airflow.
They mount the resister block in the air conditioner or heater case because of the generous amounts of air flow.
Remove the electrical connector retaining screws and the old resistor module.
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.
Hopefully the blower motor simply blew a fuse.
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.
So a problem with the vehicle s cooling system might also cause the heater to underperform or stop working.
That s why they re not far from the squirrel cage itself.
Find your fuse panel and check the fuse for the blower motor or vent fan or something like that.
These blower motor resistors get hot.
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.
Turn the air conditioning on while the car is running.
1 blower fan problem.
The air conditioner won t run properly unless your engine is running.
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.
Low coolant level counterintuitively the same system that keeps your engine cool is responsible for the heater working.
Another common problem with the air conditioner blower motor not starting up is caused by overheating.
Swap in the new part and reinstall the screws and connector.
Here is how to tell which.
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.
Thanks for your question about your ac.
