1999 GMC Sierra 1500 Question: I have replaced everything except my transfer case and my 4x4 will not shift.
check the control module for the tranfer case, fuses and or relays - Tbone1980
What does a professional scanner say about this problem? Any codes for the transfer case?? It could actually be a mechanical malfunction inside of the case! - pushrod
