Exterior Lighting Issues - '94 Magna

I recently acquired a '94 CC Magna... It has just over 80k (low) miles on it and has had a ton of really expensive work done to it in the past 3 years...  I bought it mostly to have a place to live in should we have to make a run for it due to the terrible wildfires we're faced with out here in the West...

The thing is a powerhouse, and all of the drivetrain seems to work as it should, including the cruise control and the "jake"... ( A real plus, I know...) 

But all is not well in the electrical department:  On the control panel at the driver's left is a dazzling array of switches...  But only a few of them do anything... Although the head, tail, brake and back up lights work as advertised,  (These are all controlled by the pull out switch on the lower LH dashboard, or brake pedal or turn signal..)  NONE of the other exterior lights work... No Fog Lights; No Curb lights, no Flood Lights, and no Drive Lights...  (The curb lights have ordinary 12v bulbs in them and they're still good... There's just no power getting to them...)  The interior exhaust fans don't work either...

I've looked inside the electrical wiring access door,  (First small door from the front on the driver's side..)  but there doesn't seem to be any breakers in there...??? 

I sure would like to be able to have a Porch Light at the very least... Oh, and BTW, the porch light takes two F8 T5 florescent tubes in it, which I'm assuming require 120 volts or thereabouts...  And if you decide to remove yours to clean them be careful to NOT wash the identifying info off them, which is what happened to me... Fortunately the closet light had the same tubes in it or I'd have been up the proverbial creek!

Thanks for wading through this wordy epistle... You've got sand! 

Here's hoping you can help!

The systems in your ‘94 Magna are very similar to my ‘90 Concept. All of the inoperative items you listed are DC powered so I would start with your main DC electrical panel. It’s a large panel and should be located mid-ship, likely in the first large bay behind the steer axel on the passenger side. it may be covered by a carpeted panel. If you remove the cover you can start diagnosing the problem there. Also, there is a large DC fuse between the domestic battery bank and the converter/inverter (charger/inverter). It should be exposed and easy to access. Test it with a multimeter and see if it has blown.

I have photos but don’t see how to attach them to this message. If anyone can tell me how to attach a photo here I would be happy to do so. Old BIII- feel free to contact me by email if that’s easier and I can email the photos to you. Hope this helps.
