Why is the heating on a G20 1990 Chevy Van not working?
Personally I do not know about a G20 1990 Chevy Van but the basics of heating are, the thermostat, heater control valve, heater fan and heater matrix. Does the van overheat at all, engine wise? Could be possible the system just needs a flush out. When you turn the heating dial (presuming it is a dial) you should hear a clunk which normally indicates the heater control valve switching over. Other than that, I've said all I can. Hope to be of some help, hope you get it sorted out.
