99 has pulse vacuum hubs which are ****. Get AVM manual locking hubs.

Do the 4wd lights flash once when you start the truck?

 

yes they do

 

Try this. Go under the truck with the engine off and see if you can hear the shift motor working while someone in the cab switches it in and out of 4wd. If not then its probably dead which is another common issue with Rangers. If it works then your hubs are bad. But if you are saying the lights don't come on when you shift it then more than likely the motor is dead. Could also be the switch.
