Joey Mack Posted January 4, 2023 Share Posted January 4, 2023 Im guessing its a 2002 CH? The headlight wire harness runs along the left side of the engine block, behind the oil filters. There are a few points where it is held by 'P' clamps.. they will wear through the wires, and short out the lights. also,, attached to the left side steering box upper mount bolt, , is a clamp that holds the hood wire harness... 2 square,, 4 pin plugs.. Issues can happen there.. then there is the wires going into the rear of the headlight buckets, if there is poor conditions there, the wires can be cut by the fiber glass.. jojo Quote Link to comment Share on other sites More sharing options...

Joey Mack Posted January 4, 2023 Share Posted January 4, 2023 you know,,,, another issue that plagues dash lights in these model's, is the dimmer switch... you can turn the lights on, and with the side of your finger, work the dimmer switch knob back and forth as fast as you can.. this has actually cleaned the contacts inside the knob assembly.. jojo 1 Quote Link to comment Share on other sites More sharing options...

Joey Mack Posted January 4, 2023 Share Posted January 4, 2023 pull the DRL module out of the fuse panel in the cab, and re-test.. 1 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted January 4, 2023 Share Posted January 4, 2023 did you check the fuse in the EPDM on the fire wall next to the steering column? Quote Link to comment Share on other sites More sharing options...
Vmac3 Posted January 4, 2023 Share Posted January 4, 2023 After you checked what has been suggested, there is a harness on the driver side that goes up the A-pillar to supply power to the clearance lights. remove the side carpeting to access the harness. Sometimes that harness connector corrodes and sometimes shorts out the clearance lights which will also make the dash lights stop working.
