One Window Is Inoperative From Individual Switch Operates From Master Switch
- Disconnect inoperative window switch connector. Turn ignition switch to RUN position. Using a test light connected to ground, probe inoperative window switch connector terminal "A" (Brown wire on Bonneville or Dark Blue wire on all others). If test light illuminates, go to next step. If test light does not illuminate, repair open in Dark Blue wire between inoperative window switch and master window switch (except Bonneville). On Bonneville, repair open Brown wire between inoperative window switch and splice 501 (located in driver's door near master window switch connector).
- Check inoperative window switch for poor connections. Repair as necessary. If connection is okay, replace inoperative window switch.
