A couple of months back I did the d1 transfer case shifter mod, and ever since my Mode switch doesn't work at all, and the light on the shifter telling me what gear I'm in is out. No CEL or other indicators are on.

I pulled it apart yesterday to reseat the plug on the mode switch, but it didn't help.

Any ideas?

I was thinking possibly a blown fuse, I'm gonna dig thru the Rave for that now.

 

Does "M" not work as well? I'm assuming it doesn't... I would agree that you should check fuses. I have opened up my center console a couple of times to put in a 04 CDL shifter and to replace my CDL detection switch. Both times, this caused several fuses to blow...

 

"M" only works in Low Range.
Recheck all fuses.

 

What does M mode do? You said it works in low range, do you activate it by hitting the sport button?

 

^^^ It lets you shift manually.

 

Yes, but only in low range.
