Hi, I have recently purchased a 2004 chevy Tahoe LT 4wd, I noticed the fuse for 4wd was removed, when I put the fuse back in, I cycled through auto4wd, 2h, 4h, and 4l, everything engaged and then It would not disengage from 4l. I have replaced the actuator on the transfer case, to no avail. I just purchased a shifter encoder motor, however the truck is in 4l and the new motor is in 2h, the threads do not match up and there is no way to turn them. has anyone had these problems? and if so, what were your solutions? please and thank you in advance!
