The harness that I pulled out has the rear defog, tag light, rear wipe/wash, CHMSL, and something else unused (power locks?) all in the same harness, and it goes through a hole in the body with a sharp edge and only electrical tape for protection (yes, the harness is apparently wrapped with adhesive tape.) Thanks, Chrysler! I think I will buy a stick of door edge molding to cover that sharp edge so it doesn't happen again in another 15 years. Maybe it had a grommet that long ago disintegrated. |

Seems like there was a TSB on that harness. Something to the effect of new wire/wrap with harness tape and a clip to hold it in place. -- Steve W. |

My reading of the EWDs told me that the problem I had was not possible, but it did happen. -- Tegger |

XJ 'box' Cherokee, not Grand. Other than just general noise, it's rather pleasant to drive, at least given that it's an el strippo 4WD vehicle. Drives pretty well - exceptionally well when you remember it's got a straight front axle and has a rather high COG compared to a regular car.
But my understanding is that the grand is very similar mechanically other than transmission, xfer case and rear suspension...? |
