Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
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
