2011 Ram 1500 5.7 Hemi 4WD Light

The 4WD service light would come on when I turned on the truck. I changed out the actuator and that cured that problem. Few months later when I go to put it in 4WD the 4WD light flashes and the service 4WD light comes on. I changed out the transfer case motor and it seemed to cure the problem for a couple days. Now it is doing the same thing again. Once in awhile it will engage as it should, but more times than not the 4WD light flashes and the service 4WD light comes on, Any suggestions what to check next.

Scan it for codes. Could be a module, a switch an actuator or a wheel speed sensor.

Thanks Brandon! Looks like it was a bad actuator that I put in. Changed that out again and works great now! Knock on wood!
