I am having that exact same problem with my Hyundai Accent. My heater blower only worked on the 4th setting until today that stopped working too. I'm not sure what it could be. I'm hoping someone on here can help
the resistor for the blower motor is busted blower works on high with out it
There is a resistor near the blower that is bad, known cause is high speed only.
If you are saying the Blower Motor only works on high, then your problem is a defective Blower Motor Resistor Pack. Replace it.
Blower switch and connection had a melt down.
A blower motor that only works on high is normally caused by a defective Blower Motor Resistor Pack. DRL, do not have a clue.
Check the resistor if it only works on high Check the resistor if it only works on high Check the resistor if it only works on high
Check for a bad blower resistor at blower motor
when a blower motor only works on high, it is usually due to faulty resistor board. Should be located in the duct near the blower. the purpose of this is so the air blown by the blower keeps the resistors cool.
The blower motor speed resistor is burned out.
Probably your blower motor speed resister is burned out.
