Differential not locking in 4hi or 4lo
My 2003 Tahoe's differential will not lock in into four wheel drive.
My indicator lights come on and stay on, and I can hear something activating underneath, but the front won't lock in.
In the 4lo position, it gears low, but the front won't pull.
Any suggestions?

button shift 3 or 4 button or manual shift?
if the front driveshaft is turning the tcase is ok; check the front diff, it has an actuator that engages the front axles.
depending on the build...it may have trouble codes.
