This is a common problem when the blower motor starts to go out or you have a bad connection at the blower motor or control module. Here are the locations and a guide on how to test the blower motor power and ground to help confirm the failure. Here is a generic guide to help you step by step with instructions in the diagrams below to show you how to use your car.
