i have a 2003 silverado and my service 4 wheel drive light keeps coming on and once in my indicators the neutral sign was on but it was drivin ok any ideas?

probably a switch faulty...but she really needs to be scanned for codes

I had the same issue in my 05', it was the encoder motor that needed to be replaced.

how much are those two thing would you say

No idea on cost was covered under warantee, sorry.

Its gotta be checked out...but an encoder motor is around 450 bucks.
