1996 GMC 4 wheel drive
My 1996 GMC k2500 won't shift into 4 wheel drive. When i push the 4hi
button the light just blinks and it won't engage the front tires. Checked the
voltage at the transfer case encoder switch and it had approx. 5 volts and
the ground had less than 2 ohms resistance so i am pretty sure that the 4
wheel drive switch and "brain" unit inside the truck are working ok. Checked
the voltage at the front diff actuator and found there was none. Does this
mean that the transfer case encoder motor needs to be replaced? Thanks
for any help on this.
