My 06 Trailblazer LT is stuck in 4HI. I've done all the troubleshooting suggestions elsewhere on this forum, and the encoder motor is my culprit. When I replace it, when installing the new one is it possible to plug in the harness, select 4HI, and have everything line up on the splines? Or do I need to play with the new one until it fits since I can't get the transfer case into 2HI before removing the old one?
