I have a 2007 hyundai sonata limited platinum w/automatic

Customer Question

I have a 2007 hyundai sonata limited platinum w/automatic climate controls. My a/c blower intermittently works. Sometimes when I hit a big bump it will turn on. It seems to work better when it's cold. It's it a fuse, relay or motor?? Thanks Kevin Barduca

Hello I will help you with your question,

It is usually the motor when a jar or bump will affect the operation. The bearings wear out and the contact inside is lost. If you can use a testlight or voltmeter at the motor connection when the motor will not run to see if you have power and ground to the connector that will tell you if it is the motor. If you have 12 volts and ground at the connector then replace the motor.

Let me know how I can help you with this

Thank you
