Brake light mystery
99 JGC. If I step on the brake pedal, both left and right rear brake lights
work fine. However, when I turn on the headlights (tail lights work fine) and step on the brake, my left rear light completely goes out (both the tail light and brake light are off). Any ideas on what's wrong? I know it's a single bulb, but why is it tuning off? Thanks |

It helps to have a FSM wiring diagram, which tend to be more accurate than the typical Chiltons. |

Short ciruits produce heat, smoke, fire, blown fuse and or a tripped circuit breaker... open/poor ground ! |

Is it one of these types of blubs? http://revbeergoggles.com/blub/ I'd be checking the wiring harness and any connectors for corrosion. -- DougW |

"Jeep Guy" > wrote in message ... Thanks to all for your help. Apparently this is a problem with WJs. The contact in the bulb receptacle wears out or gets misaligned. The fix is pretty easy although I have no idea how long it will last. I wonder if my lights were built by the UAW stoners featured in that news story? That would make sense. What is it with Chrysler? I hope they build a better car now that they have all of my tax money. http://preview.tinyurl.com/2a7hal6 |
