Hello all. I have a 92 Explorer Bauer Ed. I am slowly working out the kinks, and ran into a problem that I sure could use help with. My 4x4 switch is lit saying it's engaged, and in low. Of course when I drive it it does not feel like it's engaged, yet the switch is lit up. When I push the button to disengage both lights turn off as long as I have the button pushed in. I have replaced the dash switch twice, but still is lit. Any ideas on what to do? Thanks.
