I'm guessing this could be a switch? Is it easy to replace and how much would you estimate it's cost at if I do it myself?
Thanks,
Lori

4W not working?
Check 4 W drive fuses first thing.
If not fuse.
It needs to be checked for codes to see why light is on.
OBD!! scanner will not get codes.
You will need a transfer case capable scanner to get codes.
Post back any codes?
Does the shift buttons have a auto 4W button or just 4W and 2W?
If auto 4W it needs serviced with special GM blue transfer case fluid.
Ever been serviced?
