Hi Im David.....with the fan turned on to any position, go ahead and hit it a few times with your hand. see if it stops, or starts. if so replace the blower motor. if you cant get it to mess up, trying manipulating the connector and wiring to get it to act up.

Sounds like a poor method to begin a repair. I am going to go it alone. Thanks just the same.
Expert:  david craig replied 11 months ago.

Im sorry that you feel that way. another method would be to check for power at the connector of the blower motor but if its working or not, you would still need to manipulate the harness or connector to see if kick off or on. when it comes to intermittent operation of a blower motor that is the way to troubleshhoot it.

or you can just replace it and take your chances. good day.

Hello and welcome to JustAnswer!

Tapping the blower motor is a good way to quickly confirm that it is the problem, but you don't have to do so. It's quicker than electrical testing if it does happen to work, and you do do this without disturbing connections and wiring which may complicate the issue if there is a wiring or connection problem.

The first step in diagnosing the problem would be to test it's power and ground feeds with either an incandescent test light or a headlamp or fog lamp bulb and jumper wires. CAn you check for power and ground?
