I bought my truck about a year ago and my 4wd never worked I took it to gm and they charged me about 1700 to try and fix it they changed the buttons they serviced the axles and they changed my tccm module the one that's under the drivers seat but when I press on the 4x4 button they only flash then they go back to 2wd nothing clicks no noises nothing idk what it could be that my 4wd does not engage anyone help me please I really want to fix my 4wd

Did they check the transfer case at all? Maybe the harness is damaged to it or the one of the servos is bad. You could also find a np241 tcase and swap it in. Would of cost probably half of what the dealer cost. Also you might want to have someone move this to the i4/i5 section.

If it's flashing and then not doing anything then it'd either be the harness or motors on the tcase.
