I have a `93 Explorer XLT of which the 4WD is no longer working. Initally
last spring I noticed issues with the 4WD button on the dash panel that I
had to press numerous times for the 4WD to engage. About mid summer things
got worse to where I had to smack the top of the dash while pressing the
button to get the 4WD to engage. Now it doesn't work at all. I'm assuming
this is purely electronic in nature such as a switch/switch box not working
in the dash?
If this is the case, how do I go about opening the dash and
checking/removing/replacing with a new switch?
