The service 4wd light is much like the check engine light. When it is on, codes have been stored in the TCCM. You need to have your TCCM scanned by a GM Tech2 or equivalent full feature scan tool to know what the TCCM has reported as being the source of the problem.

i've seen them sensors fail more than once. get locked in 4wd and you cant get out

like swartlkk was saying get those codes read first. if your having problems disengage best bet is that front sensor, i believe its on the diff. have you ever had problems getting 4wd to engage? those actuator/motors are usally at fault when you cant get into 4wd. that was the case on mine

its not that it wont disingage is that as soon as my service 4wd light comes on i hear a click in the tccm and then the buttons are like froze
when i hit a botton on the dash to try and switch from 4wd to 2wd or vise versa it will just stay how it is until i discontect my battery and reconect it and it resets everything
