The switch to engage 4 wheel drive has stopped working. Place the truck
in neutral, apply the brake and turn the switch. Nothing happens. No
light beside the proposed setting IE. Low or High.

Where do I start looking? 2002 Ford Explorer Sport. ( It did work a few
months ago flawlessly.)

If its a stick you also need to push the clutch pedal

Unfortunately that is not the case. It is an automatic. I am hoping
that there may be a fuse or possible weak wiring link somewhere in the
chain that I can look for and change.

Any other ideas are definitely welcome.

Thanks Ollie for your suggestion.

Softly tap on the 4x4 motor on the t-case might help

They do get stuck after a while of not using it

I have a 2002 Ford Explorer XLT.. Same problem.. Worked, then stopped..
Switches did not work, dash lights not working.. Problem was with a bad
4x4 computer module located behind the glove box (module is about 3x4
inches). This "blew" when I had to disconnect battery and lost battery
power.. Found this is a problem with the computer module that was
installed. Ford wanted $500 to diagnose and fix problem, I ordered
replacement part online for $151 and problem was fixed. My dealer said
part would need "re-programmed" but online parts dealer said no.. It
was easy install,, 2 small nuts and two wire harnesses and 4x4 works
great...The new part has been redesigned so it does not happen again..
Good Luck...

I have an identical problem - would you mind providing a link to the
online parts dealer where you purchased your 4x4 computer module?

Thanks
