[CDJimmy]

I have 1998 Jimmy that refuses to engage the 4wd.

The 2HI 4HI/4LO slector switch looks like it does not have power (no light).

All fuses check out fine (not blown)
I pulled the battery and the vaccuum accuator checks out fine. What a stupid place to locate a sensitive device (under the battery and all that corrosion)
Since the battery was out - that covers the resetting of the computer

Does anyone know how/where the switch gets it power? I'm assuming a control module somewhere.

Thanks
