Window Will Not Open From Key Switch, Otherwise Operates

  1. With ignition switch "ON", open tailgate door. Turn tailgate key switch to "DOWN" position. Using a grounded 12-volt test lamp, probe Tan/White wire at key switch.
  2. If lamp does not light, replace key switch. If lamp lights, check for open Tan/White wire between key switch and window motor.
