Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
Automatic temperature control or do you have a knob for the blower speed?
The blower is fed through the switch and the blower resistor, if it only works on low speed the blower switch is the problem.
Do you have a voltmeter to check the system if I guide you?
The AC is out as well as the high blower speed?
OK, then it is the switch or the connection to the switch that has failed.
Please let me know what I can do to help you with your question
