So everything was working fine on my car until dad noticed that one of the battery connectors had some corrosion on it. He took it off, cleaned it and put it back on. After that none of my gauges are working- Fuel, MPH, Temp... nothing~! All fuses are fine and checked. Anyone know whats going on here or have had this same problem??

 

Welcome djm123, He has a 2002 Sunfire with the engine and other lights on or flashing, Can some one help him? I dont know anything about these cars.
