I had the same kinda problem when I bought my truck used in 04 turned out to be the switch on the dash itself. Take one out of a friends and give it a try before you buy.

Wish I had that kind of experience. You got the 6th sense working.
Did you fix this yet or has it stopped acting up?

The 4wd switch itself goes bad eventually. That, or the transfer case motor has a connection go bad. Both are cheap fixes

More than likely it's the motor. BUT i have a extra push button switch out of my 99 if you would like me to send it your way just to help eliminate one thing.
