When I flip the 4WD switch in my 95 Explorer, the light sometimes comes on, sometimes doesn't. If I'm in 4WD Low it sometimes won't switch to 4WD Auto, for example. If I play with the switch for awhile, it eventually gets into the drive type I want, but it can take a lot of fiddling.
BTW, the light on the dash seems to be accurate. If it's on, I am in that drive mode. If it's off, I'm definitely in 2WD.
If I leave it in, say, 4WD Auto, it will stay there. That is to say that the light doesn't randomly go off.
Have you ever had the 4X4 transfer case serviced with new fluid? If not try that first.

I finally bit the bullet and took it into the dealer. It was indeed the Light Control Module (LCM). The dealer said there was not a service bulletin issued on this problem but when I asked the service manager to talk to the Ford rep about assisting with this safety issue, it took all of ten seconds for him to come back on the line and say that they would fix the whole thing for $100. (My car is not under warranty and the LCM alone is $480). Not sure exactly what happened behind the scenes but it appears Ford would rather fix this than have an issue made of it. (This is a privately owned car that does have wigwags and other emergency lighting equipment installed. These were not a factor).

put it back into 2 wheel drive, then reverse 10 or 15 feet, this should unlock the hubs.

put a ground strap from your transfer case to your transmission. also with someone listening under the car with the key on but not running put your foot on the brake, shift to neutral and turn the selecter to 4x4 low and see if you can hear the actuater respond
SOURCE: 4x4 lights flash, will not engage into 4wd
This is called the selector motor and you may be correct this is a common problem with these trucks the selector motor goes bad and will not engage the correct gear setting you select.
