There is no 4x4 dianogstics light on dash during start up, and there are no more lights on the 4x4 switch. All fuses are okay. I had the ODB checked and it showed no problems. Its as if it has no 4wd. No other problems just no 4wd, it wasn't being used when it stopped working and hasn't been used since winter. Anyone have any ideas, I really can't afford to take it dealer unless its a serious problem.

PLEASE HELP
