> I read yesterday that if the 4wd light does not come on the cluster you can jump the wires on the plug that’s for the actuator if the light then comes on it’s the actuator gone bad. I will have to check it. I do not know if the light even comes on or not, I have not tried to put it in 4wd yet. it seems pretty common on these and a cheap fix, so fingers crossed.

Yes you can jumper the signal wire, but that doesn’t dynamically test the power and ground supply circuits to the actuator. That being said it needs and actuator 99% of the time. Some of the older trucks actually require a retro fit kit to the newer style actuator, however I can’t remember where the year break is.
