4x4 Light always on

[Pr0jeCt]

I recently went on a trip to the airport, about a 2 hour drive. When i got to the parking garage i noticed the 4x4 light was lit up on the dash, and on the pushbutton switch. oh, 95 bronco is what i drive. I currently dont even have the front driveshaft installed so its not a big deal if its locked in 4x because well, it wont do much.. But im wondering WHY the light is stuck on all of a sudden?. Last august i had to pull the tranny to do the front seal and it has been fine up untill my recent trip.

Any clue as to why it is stuck on? is this an indicator of a common problem? any help is much appreciated.

yo P,

Indicator Lights Don't Register the Correct Information

Ranger, Bronco II and Explorer have indicator lights in two locations. There are lights on the dash and LED indicator lights in the switches. Other vehicles have only the dash lights. If the dash lights on any vehicle don't respond, look for no power or a burned out bulb.

If the lights are on all the time, look for a short to ground. Also check to see if the shift control module is activating them all...this is a malfunction.

If the LED lights, in the buttons, remain on all the time, first check to see if the dash lights are also on. If the dash lights are not on, this means that the dash lights have burned out. The LED lights are on because a low current is still passing across, enough to light the LED.

If no lights illuminate as you go through the shifts and ground power and bulbs are good, then the module is at fault or the motor has stopped at an intermediate point.

Most likely in that is;
