Instrument Panel & Tailgate Switch

Turn ignition switch to "ON" position. Using a 12 volt test lamp or a voltmeter, connect one end of test equipment to ground and probe the "RED" lead. If current is not available, repair feed circuit. If current is present, probe "BROWN" lead with switch in "UP" position. If current is present move switch to "DOWN" position and check the "TAN" lead for current. If current is not present, replace switch. If current is present check window switch in the tailgate using the same procedure.
