05 Tahoe 118k miles. Tahoe goes into 4hi or auto 4wd when driving.

What is your question?

Tahoe’s shifts into for low or 4auto when driving and low speeds(20-3mph). I have replaced the switch but that did not resolve the issue. Went on to remove the 4wd fuse in the cab and unplugged the actuator but the switch still showed 4wd still trying to engage but could not. What else could be the issue if not the switch not the actuator.

What makes this problem better or worse?

No indication of being better or worse, happens sporadically.
