and download the proper wiring diagram for your truck. Start with the dimmer switch, use a voltmeter or 12V test light to check for continuity, bad switches, bad/corroded connections, burned/broken wires, etc...

Thanks for linking the wiring diagram. That will be a helpful resource. I plan to check with a test light before moving forward with any replacement switches...
