Does the CDL actually ever engage? or engage and then dis-engage? IIRC there is the CDL switch on the tranny and the actually switch that it engages the actuator (there are 2 more but can't remember off the top of my head). There is a couple threads on testing the relay for the center diff. I thought mine was toast, but a local chapter guy helped me test it out.
All the same, my guess would be to pull the relay and run some of the tests on it.
