Neutral light on 4WD selector switch stays on and won't shift to 2hi 4hi Auto 4 low
What is your question?
4WD selector neutral light stays on and can't select other modes My truck has the 4 buttons on the dash 4auto 2hi 4hi and 4low. I replaced the dash switch but nothing else. I hate to start replacing encoder motor, TCCM etc would only be swapping parts. I read several different problems but none saying what fixed it
What makes this problem better or worse?
never changes
How long has your 1999 GMC Sierra 2500 had this problem?
RepairPal Certified shops can diagnose and repair your 1999 GMC Sierra 2500. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Sounds like a system malfunction that will require hands on diagnostic testing.
I wouldn't replace a single part until performing diagnostic testing using a diagnostic tool that can show any set trouble codes and also monitor component operation.
