| Post subject: | Light bar is dead....again. |
I had a Renegade light bar installed on my '03 KJ Sport and it worked fine for a while. Then it was dead. The tech replaced a relay of some sort for free and it worked fine again....for a while. It is now dead again. The dealer that did the original install and subsequent relay replacement is out of business so I need to do some self-diagnosis. Exactly where is this relay? I'm presuming that it's in the light bar assembly. The switch on the dash is showing power. What is the part number for this relay and how can I check it? |

It's more likely that the switch fell apart than a relay went bad. Pop the panel out and push on the switch housing to make sure it's still together. Mine "unsnaps" all the time... not by much but just enough that the switch doesn't make electrical contact. If that's not it, you're going to need a DMM or a low-voltage test light to trouble-shoot. We should add an electrical section to the forum so we can keep track of things like this. |

If when you press the button,you hear a click,then your relay is good. If good relay,check fuse(located by all other fuses).You should be able to trace the wire that comes off the switch,to the slot that they placed your fuse(should look a little different than the others). My fuse went bad. <note to self:change lightbar fuse> |

There is lights up in these things? I thought they were just up there to look cool. |

Pull the a-pillar cover. Disconnect the light bar harness. Use a test-light or multimeter to probe teh wires coming from teh dashboard side. Turn the ignition to run, press the light bar switch...do you have power to the plug at the a-pillar? If yes, plug the connector back in and pull the light bar cover on the roof, and check the harness connector at the light bar (drivers side). |

I agree with the switch idea. I have had problems with my switch and it sounds like what you describe. Just to be safe though you should buy a new light bar and give the old one to tofu. |
