Windows Operate From Master Switch Only
Turn ignition switch to OFF position. Remove and disconnect master window switch. See POWER WINDOW SWITCH under REMOVAL & INSTALLATION. Ensure window lock-out switch on master switch is in OFF position. Measure resistance between master window switch terminals No. 19 and 20. See Figure . If resistance is less than 5 ohms, repair open in Red/Light Blue wire. If resistance is greater than 5 ohms, replace master switch. Clear DTCs and retest.
