Hi, i have an o4 trilblazer that had a cracked transfer case np8, I replaced it with a used one, it came complete with shift motor and all sensors. When i switch it in to any mode awd, 4 wheel high or 4 wheel low. the light flashes on what i selected but then goes off, and the light on 2 wheel high stays on the whole time. The 4 wheel drive never engages.
