Hi, depending on the vehicle, there can be different controls. Standard control, 4hi, use in slippery conditions, never on dry pavement. Just push the button, and it will engage. 4low is for extreme conditons and the transmission must be in neuteral to engage 4lo. If you have auto 4wd button, just press the button in slippery conditions. If you have a denali, it is all wheel drive, and there are no buttons to push. So, depending on the model, there are multiple ways, but pushing the button engages it. Good luck...Goop
if it is a lever type and not automatic 4WD. You have to manually get down and turn the hubs clockwise to engage or couter clockwise to remove from 4WD. then Push the lever to 4L or 4Hi. If it is automatic. You press a button to engage 4wd.
Sounds like yoou have a short either in the switch pod or in the 4wd electrics. Check for pinched wires or bare wires grounding out at the front axle and at the transfer case.
I have a 1994 ford f150, my 4 wheel drive keeps trying to engage by itself even without me touching the automatic hub button....at time you can even hear it engaging and disengaging by itself, the low range light even comes on (dimly)...what could be the cause? the transfer case motor looks good and so does the wiring.
