Thanks for reporting back, glad you got it fixed. Did the old GEM look to have any water intrusion evidence or similar?

It had some, umm, "fuzzy green stuff" all over the components inside. I tried to clean it, and I think all I succeeded in doing was completely killing it. Interior lights didn't even work after that. So, yeah, it had something going on with it, but I don't know what.

Glad you got it working again. Where is the GEM located? Do you have a pic of it?

Plug and play. That's good.

Same question here. Where's the GEM? What does this acronym stand for?

GEM: Generic Electronic Module

Mounted to the back of the under dash fuse block in 1999-2001.

2002-2003 GEM was replaced by the VSM : Vehicle Security Module. I'm not certain where the VSM is located.

Thanks. I'm pretty dependent on 4WD when I head off-road. And I worry about the reliability of the electrically switched 4WD system. I've got manual Warn Hubs, but I'm still reliant on the factory 4WD actuation of the transfer case. Would be nice to have a carry-along spare, but not at those new item prices. Maybe a salvage yard?

Might have to research this some more to determine how year and vehicle specific these GEMs are.
