4x4 won't disengage

[98 2-DOOR]

4x4 engages in all (Auto, 4 High, and 4 Low) after driving for about 30 seconds in any of the 3 drives, the service 4x4 light comes on/shift button blinks and it will not shift out of 4 wheel drive. I have to stop, turn off ignition, then when i start it back up it will go back into 2 wheel drive. Any idea on what the problem is?

have your selector switch tested,or just change it .could be a fluke,because the same thing happened to my dodge ram and i fixed it by swapping out the switch.Im sure other members would chime in........

i just noticed this, when testing the switch, i heard a clicking noise under the dash/floorboard area happen when the service 4x4 light comes on??? Also, when the ignition is turned off, that noise happens again, then when i turn the ignition back on i am able to switch back to 2wd...wierd?

I will have a troubleshooting chart for you afterward that will help determine if it is your front axle or the control module both are easy to do.

the indicator on the switch that tells you what drive you are in.
