4x4 control module (4x4 flash problem)

I just bought my 2002 Explorer Eddie Bauer Edition from a large dealership that claimed they did this great inspection on all of their used vehicles. I've owned the vehicle for three weeks now. I only got to drive it for the first week. It's been at the dealership because of 4x4 issues the rest of the time. I first took it back for work because the 4x4 High light started flashing and 4x4 would not engage. They replaced the 4x4 High switch and called me to come get the truck. I drive about a mile and the vehicle jumps into 4x4 mode on its own and will not switch back. I made the dealer tow it back to their shop. I just got a call that the truck is ready to be picked up again. They say they have now replaced the 4x4 Control Module. We'll see if that did the trick.

I replaced my 2002 Explorer's 4x4 CM. Same symptoms as most everyone else. Bought the new CM online from Direct Ford Parts for $140.00 plus shipping. Make sure you have your VIN number on hand and they will make sure you get the right CM. A easy install. Took about a half hour.

Ok Here's a strange one for everyone. I had been slacking on replacine the 4x4 module and my wife had been driving the truck. One evening she calls me and tells me the truck is running very rough and feels like it is stuck between shifts. Since that day the module which the dealer told me is bad has acted fine with no flashing. The gremlins must really be messing with me.

4x4 cm
I have a 02 explorer. Which I cannot get to go into 4wd neither high or low. When I puch the button to try to get it to shift into nothing happens, the light doesnt even come one. Is this what happened when everybody else's went bad?

Replace your 4x4 control module... (also from what I understand, the all wheel drive will not work when this is bad as well, which mine didn't).
EDIT - Here's another thread about this (where I posted my question about it)
