Question about Chevrolet K2500
The fuse for the 4 wheel drive keeps blowing
Posted by Anonymous on
Need more info. Does it blow fuses all the time, has this problem gotten worse or was out of nowhere, Does it happen when you go into 4wd or out?

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.
