I would start looking at the wiring harness for rodent damage or just age cracking of the insulation on the wires.

Does the car have a new (main) battery?

Mice and rats can get just about anywhere in the harness, you simply have to get a good light and start tracing wires.  I'd start with the engine bay and any wires under the vehicle first as they are the most accessible to the rodents.
