Have you had a mechanic look at it? When did this happen? After some work was done or a wreck or a flat tire?

electronic center diff IS THERE ANYWAY TO ENGAGE IT I DO NOT KNOW IF ITS BEEN TOWED JUST BOUGHT IT THEN FOUND OUT THE 4X4 DID NOT WORK [IN MUD] SOMEONE TOLD ME IT COULD BE A SELIOD COULD BE BAD [COULD IT] IF THE electronic center diff IS BAD IS THAT ON THE BACK OF TRANSMISSION??
When everything is working (no failed devices) slip is detected and the pulse train sent to the duty solenoid C is altered to help distribute power to the front or rear of the car away from the slippage. If 12 Volts continuous is supplied to the solenoid (by putting in the fuse in the proper slot under the hood) the system becomes front wheel drive.
I suppose removing voltage from the solenoid or if it were 'bad' (open) would give you 4WD all the time - UNLESS the wet clutch pack were bad in the tailshaft of the tranny. Assuming your rear diff isn't blown or some odd part of the rear drive line were missing - I'd say the clutch pack is burnt up.
