My trusty commuter has started an odd problem. All at once the ABS light came on, the dinging alarm for keys in ignition and headlights on stopped working, some light won't work and the most annoying radio presets clear each turn off. Since it all happened overnight I was thinking fuse but the 20amp in block near driver door is fine. Any ideas?

 

Could've been a bad connection between the battery cable and the 3 - 4 connectors stacked on it. That was the case with my '92 Corsica because of a **** poor and very cheap design. With the 92, that connection is in the engine compartment on the passenger side -- should be able to find it easily if you follow the positive cable.
