    If you are referring to the blower fan it is probably the resistor.
    Blower control module is more than likely your problem

    I thought you meant the interior fan too. Sounds like the motor fried.

    Yep... the motor is gone. Don't go aftermarket. There have been "thermal events" with aftermarket fans.

    The aftermarket ones fail within a few months then only work on high which makes it overheat and cause a fire.

    Blower Motor

    I have checked the blower motor connector with a test light and it works (the light lights) so it is not the connector. I ran the test light from the negative pole to the blower and nothing. Can I say now that it is the blower motor? Why not aftermarket? What starts the fires?

    Don't know what starts the fire, but there have been multiple reports of thermal events ie. fires when using the aftermarket fan/motor assemblies. Knowing this, I wouldn't use one.

    Amazon.com

    Brother, I bought mine on Amazon.com and I haven't had an issue as of yet. I did go to Autozone and Advance Auto and was very frustrated!!! The fan blower motor and cage came together as one package for the price of the motor itself.http://www.amazon.com/gp/product/B003XX3ZTO. I paid $47.00.

    I know this is an old post, yesterday I jump in the MM and the A/C compressor kicks on but the fan blower does not (interior). All O rings been changed by the way. I use my backhand and slap under the dash while in the driver side seat and bam it turns on. It appears that the resistor is on its way out. Thoughts, comments appreciated.

    I'd love to know what you hit since the blower control module which is almost always the point of failure for this problem, exists under the hood on the passenger side mounted to the heater box.

    The "kick under the dash on the drivers side" is the "oh no my headlights went out" lifehack.

    O rings are for vacuum, not electrical.
