4wd Actuator not engaging
As it says, the actuator on the front axle of my 90 k1500 is not engaging when I pull the lever to 4wd. I can see the front driveshaft turning, so the transfer case is good. I know its an electrical problem. The light in the cab for 4wd will come on every once in a while, but will turn off again in a few seconds of driving in 4wd. What are the common spots to see problems with this system's electrical?

The actuator is pretty easy to pull from the axle. Take it out and have someone shift in and out of 4wd. Make sure it's working properly before you start pulling apart wiring harnesses.When you hear hoofbeats, look for horses not zebras.
