4x4 Explorer

My son has an old 4WD Explorer.

Last week in the mountains he tried to engage the 4WD (dash button) & it falied
to engage. We solved the temporary problem by buying chains.

Now he's out ot the snow & cold, the 4WD stll won't engage but he hear's a
"click" whne the 4WD switch is pressed.

Hi's car sat for about week in 30F weather before the problem.

Funny thing was I met another group of kids (when we were buying chains) with a
much newer Explorer that would enage its 4WD; similar situation.


Anybody got an idea?

What year?? Some of the first push button ones had a module involved
that operated an electric motor that did the actual shift at the
transfur case. The module, in alot of the ones I fixed, was the usual
problem. Don't rule out the switch or the motor & diagnose it properly
but thats probably where you'll wind up. Good luck.
