need help diagnosing 4x4 issue

[Jadikona]

I have checked all circuits fuses and relays everything is good but the 4x4 wont engage or anything no light will turn on at all and from what I know the 4x4 hasn't been used in my explorer in a couple years. I need to know what to check out and how to go about it.

Yours has a separate 4x module. You've had it checked? Not sure how to, others should be able to speak to this as it's been discussed before.

Just a quick search came up with this thread

Give it a look, hopefully someone with an '02/'03 will review and respond.
