2003 GMC Sierra 4wd 2500 HD
Any one have any of these issues?
1. Transfer case chain rub hole in case and makes noise
2. Ignition module come out and get out of sync
3. 4wd doesn't seem to engage
4. Speedo sticks and pegs when going less than speed limits
5. Cruise control doesn't seem to work now, could it be from the above problem

If anyone has had any of these problems let me know what you did to correct.

 

I think the Tranfer case has a common wire problem, not sure. The cruise and speedo problem sound like the VSS(vehicle speed sensor) is bad.

 

I just slid the on switch on Duh, I thought I did that maybe the switch has a problem. Is the speedo thing something I can fix?
