I’ve been having issues with my 4WD buttons. Vehicle is a non- autotrac 1996 RCSB with the 5.0/Auto. The orange led’s on the pushbutton selector for the 4x4 randomly stop displaying what mode the Transfer case is in. However the backlight still works for the buttons reguardless of whether or not the orange indicators are working. Throughout the day, it will randomly display the orange indicator lights, and they stay on for 30 mins or so before turning themselves back off. Every time they light up, the t-case will shift between 2/4hi/4lo perfectly fine. However when the lights go out, i am unable to shift the t-case until they decide to randomly come back on. I replaced the pushbuttons and the problem went away for a week, then the new buttons began to do the same thing: intermittent functionality, but the backlight works regardless. Is my TCCM Module under the dash going bad? The t-case shift motor works fine when the buttons are illuminated. Front diff actuator is only 14 months old... please help!!!
