Q: Four-wheel drive encoder motor not working properly.

Hello, Since this recurring regularly the vehicle should be scanned for code. There is a good chance that the wiring to speed sensor on the transfer case has become compromised over time and the wiring harness needs to replaced. This was addressed in TSB 05-04-21-003C.
