    99 Tahoe 5.7 NP8 t-case refuses to shift into 4wd. Blows its fuse when it tries. With the encoder off I've tried to shift the t-case by hand and it will not shift much past the 2wd location. I can shift into neutral. It will be a while before I can remove the t-case and have a chance to do any repairs. I'm basically looking for info as to what may be binding internally to cause it to not shift in into 4wd?
