The rear running lights, licence plate and instrument panel lights do not work. I checked all the fuses in both the power panel and fuse panels. Also I turned the car on and off several times as well and turned the main head lamps on and off and worked the instrument light dimmer. brake, head lamps, turn signal, and reverse lights work. Id there a special electronic reset procedure required?

    Make up a long piece of wire with an inline fuse in the wire attach one end to the positive terminal of your battery and try momentarily supplying power to the brown wire at either the tail light or licience plate light (which ever one you can get to easier). If the lights now work the bulbs and circuit from that point back are good and you need a wiring diagram and voltmeter to proceed further. Brown at the light switch itself should be live when the taillights are turned on or the switch may be defective.

    The problem may be the wiring harness attatched to the trunk lid hinge. When you open/close the trunklid, it causes the wires to bend and eventually break.
