94 Ford Explorer 4x4

94 Ford Exp 69K. 4x4 is not working. Some times the lights next to the selector buttons on the dash will both light dimily. Nothing is heard when pressing either. Some times the lights go out. The other day pulling into the drive way they both lit and the 4X4 indicator on the dash came on. The car was not in 4X4 because I drove it on the road and made some tight turns and it would have been obvious if it was in fact in 4 wheel. This light stayed on for approx 2 hours then went out and both push button switches went back to dimly lit. I have read posts about looking the the 4X4 module in the rear driver side panel and watching led's or pressing the reset button. On mine there are no led's or a reset button only a black box. Has anyone had these issues? Any Ideas?

On my 92 there is a white square shaped button pointing down that you can press upward on, I assume it's the reset button. What typically goes wrong on these systems is that the multi prong rotary switch that's built into the shift motor on the transfer case goes bad. You can disassemble the whole motor and clean up the switch and make it last a while longer but having done that twice with the last repair only lasting a few weeks I just replaced the whole shift motor assembly. You can buy new motors for about $125 and replace it in an hour with basic tools while laying under the vehicle.

The lights will come on whether the autohub engages or not. Most likely your autohub is not engaging or is only engaging partway and then ratcheting when you put load on it. However, if you are doing this on a hard surface and while making tight turns you are overloading the hub mechanism and it may well ratchet under those conditions. It should not make any noises when in 4x4 mode when you are going straight ahead on a firm surface because all the parts, engaged or not, are turning at essentially the same speed once the transfer case locks.
