1997 Plymouth Voyager

My gauges and digital Odometer, tailights, right door and rear vent windows do not work. The brake and airbag lights are on.

The fuses under hood and under dash look good. Are these problems related and what is the fix. Thanks

electrical nightmare, bad grounding? check wiring diagram for ground wires common to the effected accesories and their (ground) locations. wet carpet? rust? windshield cracked or replaced?

The brake light might be from low brake fluid level, check that first BEFORE driving. The airbag might need a code reader, but that is where you can start because you will at least get a lead. Normally when the instrument cluster on these cars go, it is because of a bad solder point on the back side of it. Just google it.
