'97 F150 4.6L Other day got in truck and started it and once running the 4wheel drive lights(hi/lo together) lit and flashed a few times then wet out. Now trans. case is stuck in 4 HI and can't get it out. flipping the switch does nothing and the indicator lights remain off at all times. I pulled the switch out of the dash and using multi-tester can only get 5V in what seems to be the power lead for the switch? Now what?
