Door Lock, radio Electric problem

I see from other posts many similar problems...

My power door locks, radio, open rear hatch button, and overhead interior lights all stopped working at once. This is a 92 Caravan. The only fuses I see are under and to the side of the steering column (inside), and they are all good. I have checked under the hood and unless they are well hidden I can't find any fuses there that others seem to have found. I hope it is not the wiring harness like one post said. Anyone know where to find fuses under the hood for a 92 Caravan? Or have pointers to which Relay or something else might tie all these together?

Thanks,
David

I found my problem.

From the battery positive terminal, I followed a wire bundle along the driver side frame, back to where the Windshield Washing fluid container is, right by the hinge of the hood. It was hidden on the bottom back in the corner, but there I found a wire that had corroded in half. Snip, snip, splice, splice, I am back in business.
