#111 of 236 2000 silverado front drive shaft concerns by gwhitney Oct 14, 2008 (4:00 pm)
I have the electric shift and I hear it change to all positions, It also appears to be working, however when I have it in 2 WD is the front drive shaft supposed to be turning all the time or is it supposed to be disengaged. I had my wife move it in the drive way and it turned both in forward and reverse. I also tried to turn it by hand just to see if it might be free wheeling. It is not. It is either engaged at the transfer case or at the front axle. Is this normal? It all stared to concern me when the service 4wd light came on. It has happened twice now and goes off when I restart the truck. Both times I was driving in 2WD. there were no codes / messages logged in the computer when it was checked.

I want to put dci controls on my 2008 gmc and was wondering if i could just buy the parts, without having to programing the computer? Replies to this message: obyone (Oct 21, 2008 3:46 pm)

Replying to: basgmc08 (Oct 21, 2008 2:54 pm) Are you asking about this?   DIC   If so, yes you can order the part, install it and it will work with no programming needed. However, sorry to say it is on national back order. Guess it's a popular thing to do.   There may be another source that has it. Try checking here:   DIC switch

Thank you! The dealership didn't know if it would even work! What about dual climate will it be the same way plug n play so to speak? Replies to this message: obyone (Oct 21, 2008 9:24 pm)

Replying to: basgmc08 (Oct 21, 2008 6:35 pm) I'm not absolutely positive on this but as I remember the pin out on the backside of the dual is different. Not doing so would make it way too easy for people to upgrade.

Replying to: airtindi (Oct 29, 2008 8:23 pm) For sure you have an electrical short, start out by checking all your fuses, your manual will show where the fuse boxes are. bb   The back of the insteerment cluster has a main power supply plug that supplies power to the inst. cluster as I recall the power to 4wd is independent from the inst.cluster power supply. This makes me think it could be a main ground short.   There are a number of ground straps from the engine to the frame all tying back to the battery ground.   You need a volt meter The cluster is easily removed 1. Trim bezel 2. Cluster screws   Sorry if that sound like a lot of unknowns to follow-up on, the fact is that there is not a simple answer with out checking a number of possibilities.
