1999 Blazer Service 4x4 light

[Travl_1]

I have a 1999 Chevy Blazer, The service 4x4 light will not disengage.

I have Cleared the Code , it set code 308, implying that the decoder motor was bad.

Replaced both the decoder motor, and Shift motor.

and cleared code, and it re sets. Scan tool shows its locked in 4h, despite physically being in 2h.

the 4 button automatic shift wont work at all, Any idea's on what im missing?

Code 308 is a short to ground or a bad motor.
To test get the repair flow chart for code 308 and go threw it step by step.

A factory repair manual or a all data online sub has the repair fow charts.
