I have a '98 1500 4x4 with the pushbutton setup. Driving out to the beach today, I was getting a bit of fear because I would push the 4x4 button, and I could not tell if I was engaged. I hit the switch to go to 2WD and back to 4x4 hi, and finally felt it engage. Normally when switching, it should flash, then stay lit correct? At one point I had my wife get out to verify she could see all wheels spinning when I stepped on it. My controls don't light up. After being stopped, and starting back up, I noticed the 4x4 hi switch was illumintated. But then after awhile it turned off (no lights lit).
