2001 blazer with 4 button switch. 4wd is working properly. It will switch between 2hi, 4hi and 4lo and indicate that it has. The problem is that the neutral light is now coming on with the other indicator lights. The neutral light will flash and then illuminate solid along with the amber (4hi and 4lo. not 2hi) light. There is no service 4wd indication so i'm assuming there is no codes or am i wrong on this? I just spent 2 hours searching but the only similar problems I can find is for 4wd that isn't working.

Any help or ideas would be appreciated.

Thanks, Brad
