i changed my transfer case control module and now my vehicle will not go back into two wheel drive. it is stuck in neutral position, when i try to change positions with the switch it blinks and all the lights go out, then my service light comes on.

Hello,

Is sounds like you have a fuse or the transfer case encoder actuator is out but to be sure lets run a simple test. There are five fuses that run the system.

Check to see if the encoder is getting a signal and if so replace the actuator.

You will need to raise the car up safely to get the job done.

Please let us know what happens.

Cheers, Ken
