What procedure are you using to engage the 4H and 4L?

This may not be a part cannon problem.

 

Have you tried using a scan tool to check for codes and control the various actuators one at a time to see which one(s) may not be playing nice? Do all the actuators test within spec? Do they all have power/ground?
