Intermittent on/off: battery light, check engine light, speedometer. on 2002 Honda Civic

Heater on feet doesn't work (but upper and windshield do work). Car quit running while waiting at a stop light - started up ok, then acted as though it had emphysema. Dashboard light works in some places and not others (rather like a worn out string of Christmas tree lights where a good many are duds). The dashboard light not really working started last winter; the first check engine light 3 wks ago; the heater problem 2 wks ago; the rest of it yesterday.
