Four wheel drive not working - Cars & Trucks

SOURCE: Four Wheel drive not working. Blows fuses.

Hi:
Your four wheel drive push button system has only 3 components, so there is a way to narrow down what is blowing the fuse:

the system includes the push button panel and indicator light, the shift control module, and the shift control motor.

The shift control motor is the only part that can draw enough current to blow the fuse. If for some reason the transfer case is jambed up, that could blow the fuse too...So if you are planning on attempting repair yourself:

first, unplug the connector off of the shift control motor, and see if the fuse still blows.. if not, then remove the shift control motor from the side of the transfer case and plug it back in to the harness and see if the fuse blows. If so, then the shift control motor is bad, if the fuse doesnt blow then you need to check out your transfer case.

There is a four wheel drive relay unit located up under your dashboard on the passenger's side that has gone bad. 2 bolts hold it in, and just a wire bundle connector to plug into. Costly to replace. Maybe about $200 just for the 4 WD relay unit.

If the 4x4 is engaged, then look at the axles and transfer case, see if the axles are spinning. If they are spinning and wheels are not, then you need to lock your hubs so they spin when axles spin.
