Advice needed. A bunch of electronics failed all at once.

Everything running fine. Parked the car for 3 days. Returned from business trip.

I get in the car, engine starts fine. Driving down the road I notice:

• no power window operation
• no turn signals (emergency flashers *do* work)
• no fuel gauge operation
• no tachometer operation
• no temperature gauge operation

All of this worked when I parked the car. No rain or cold weather during the trip. Everything else electric I could find works fine.

Any advice on how to start on this? I assume this would be multiple circuits, so multiple fuses would be in play.
