Why is my Hyundai blower motor not working?
The resistor going bad is a fairly common problem which is easily fixed though it is an issue which is often missed. If this does not resolve the problem then check if there is a problem with the outside ambient air temperature sensor. If this shorts it breaks the circuit and the AC will not work.
Where is the speed control on a Hyundai blower?
There appears to be a problem with the blower speed control which is located next to the blower motor below the blower case. Check the circuit with a test light or voltmeter, especially the wiring from the motor to the speed control. If there’s no problem so far, check the blower motor itself which might have failed.
What should I do if my blower motor is not working?
Check the fuse in the fuse box rated at 30 amps which is for the Blower. Also check the fuse on location 5 of the interior fuse box rated at 10 amps. If both fuses are good then check the blower motor relay which might need to be replaced. If the motor still does not work then in its high position check for power and ground.
Can you change the resistor on a Hyundai blower?
If that is good try the blue wire next which should run the blower on medium then the white wire which should run the blower at low speed. If it runs properly on all three speeds it confirms that the resistor is good. Merely changing a resistor is no guarantee that the replaced resistor is good.
