I replaced it with an after market unit bought through monster autoparts. At first after installing the new unit the selector switch light lit up properly and I could select between A4WD 2HI 4HI and 4LO but the front axle would not engage. Now the selector switch is stuck lit on A4WD and will not change. The encoder motor makes a cycling noise like it is trying to shift between gears with the key off and out of the ignition. (does it also with the engine running) The front axle actuator will lock the front axle. Anyone have this problem? This drive 4wd system ihas been an absolute pain. any ideas? Any suggestions would be appreciated.

To many codes.
With that many cods could be transfer case computer or wiring.
What Silverado and what transfer case?
Were codes cleared and retested.
For what code popped first.
Clear codes and see what code comes back first.
To test and repair transfer case problems you will need a good transfer case scanner and some good repair info on the repair flow charts.
Not just throwing parts at it from somebodys code check.
