Have a 94 325i that reads nothing on the gauges. Radiator broke and took awhile to replace. Battery went dead, recharged it and replaced radiator. When I started the car the gauges would not work. No tach, speedo is way off goes as far as 20 mph or so and that is it, no fuel or temp readings, check brake fluid light is on as well as parking brake light. All fuses are ok...stumped.
