FULL TIME Indicator Does Not Illuminate With Mode Selected

NOTE: This test assumes that transfer case and linkage are operating properly. Following procedure will help locate a short or open in FULL TIME light circuit.

Turn ignition switch to OFF position. Remove and inspect fuse No. 9 (10-amp) from junction block. If fuse is blown, repair short to ground in White/Black wire between instrument cluster and junction block. Replace fuse. If fuse is okay, go to next step.
Turn ignition switch to ON position. Check for battery voltage at power side of fuse No. 9. If battery voltage is not present, repair open in Dark Blue wire between ignition switch and junction block. If battery voltage is present, go to next step.
Turn ignition switch to OFF position. Disconnect negative battery cable. Disconnect transfer case switch harness connector. Check continuity between ground and Black wire terminal at transfer case switch harness connector. If no continuity exists, repair short to ground in Black wire. If continuity exists, go to next step.
Connect negative battery cable. Turn ignition switch to ON position. Connect a jumper wire between ground and Black/White wire terminal at transfer case switch harness connector. If FULL TIME indicator illuminates, replace transfer case switch. If FULL TIME indicator does not illuminate, go to next step.
Turn ignition switch to OFF position. Disconnect negative battery cable. Remove instrument cluster. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Ensure transfer case switch harness connector is still disconnected. Check continuity of Black/White wire between terminal No. 7 at instrument cluster harness connector C2 and terminal at transfer case switch harness connector. See Figure . If continuity exists, replace FULL TIME indicator bulb. If no continuity exists, repair open in Black/White wire between instrument cluster and transfer case switch.
