4WD wont disengage

When I have the TREC fuse in my truck, my truck locks into 4wd and I cant get it into 2wd. When I pull the fuse out, it stays in 2wd.
Anybody have any ideas on what could be causing this?

The front sensor is easy to replace - I did mine several years ago! Check out 1AAuto or You tube it. There are two. To find out which one is defective, unplug and switch sides both sensors. I can't remember what transpires so that you know which one is defective, hence checking out the above sites. I also bought the sensor very cheap on Ebay or 1AAuto.
The radio... I would pull the negative cable off the battery, wait for 5 minutes, then hook it back up. Then try the CD changer. Sometimes this works to reset the radio electronics. If not, try LKQ if you have a newer truck, they may have one that is cheap but still working fine.

Good luck!
