Not a good time....whew it is hot. My fan motor slowed down, sped up slowed down....sped up and now does not work. I must have deleted my manual and can not test fan motor, resistors and such. Can someone point me to or send me a link for a manual. where is the darn fan anyway...it is too hot to spend a lot of time guessing here...... thanks... |

There was a recall on the fan motor back in 07; check jeep.com to see if yours is due. |

Mine had the recall, and went for 1 1/2 years before the resistor died. Got a new resistor from Rock Auto. |

Did it loose one speed at a time? If so then it's most likely the resistor. It's in the heater/ac duct behind the glove box. It's a funky little one and can be replaced by a more robust one from a 03 Sebring. The original KJ resister is a circuit board and the Sebring one is a real resistor on a ceramic body. Mine went out at around 3 years and 25k miles  I found a thread on "the other jeep forum" is how I learned about it.

10 min fix. Easy access behind glovebox. 10mm socket and phillips screwdriver. Good thing the resistor is around $25 at any mopar dealer. |

I was hoping that was where it was. I hear when the resistor goes I would have high speed. I got nooooo...speed. I will pull the box out today and check for power along the circuit. Thanks. |

On mine low died first and before I got the new one, I had nothing. Thought you would like to know. |

I thought it would run on high with a bad resistor, since that is the only speed that does not use a resistor. I would say fuse, motor, switch or wiring. |

Ok..now I am really feeling dumb... It took 3 minutes to pull the glove box and drop the cover. I see the fan but do not see any connectors to drop it from the system. Does it twist out? My sight is getting worse in the dark. When I bump the fan it runs slowly and clicks on something and soon stops. Any one have a pdf of the service manual? |

Sounds like the motor is dying. That is no resistor problem. Compliments of Sir Sam viewtopic.php?p=603027#p603027 |

Thanks flman...the manual helps a lot...Jim  All I have to do now is keep a hammer on the passenger seat until the replacement fan arrives. I just thump the darn thing when I want more AC! |

It runs the same speed on all settings when I thump it. I will check for foreign matter that may interfere with the blade. It runs for a while and then I can hear it slowing down and sputtering to a halt....thumping away on these hot days. Once the fan motor comes I will go into it. |

If it works on high speed any other weirdness should be caused by the blower resistor. If you want to upgrade and don't want problems with that anymore, go see this thread: http://www.lostjeeps.com/forum/phpBB3/viewtopic.php?f=3&t=47156&hilit=blower+resistor |

Whew....I have AC. As soon as I plugged the fan in to test, it ran. All 4 speeds work. thanks for all your help. Jim |
