One problem related to underhood wiring has been reported for the 1999 Chrysler Town & Country. The most recently reported issues are listed below.
The large (1. 5in. ) bundle of wires that goes from the battery/fuse box to the starter/other places. . . Goes through a cutout in the bottom/front of the vehicle this bundle rubs with vibration untill the insulation is gone. Short causes the fire. My brother's van is built the same way.
