On my 1974 corvette, my heath stopped working a few months ago. one day it worked fine then I drove it the next day and the heater stopped. What could cause the heat to stop working?

Does the fan work at all? Could be something as simple as a blown fuse.

When you say the heat stopped working, do you mean the fan isn't blowing or that it is blowing but the air is cold?

cold air=low water level, thermostat open(is car running correct temp on guage?)temp setting on console not correct, kinked hose, do you have a shut off on the heater hoses(manually or one controlled by the heater control)
is this a new car to you??
