Assuming the blower is working, the reason for no heat could be, low on coolant due to leak in coolant system, thermostat stuck open, heater core plugged or temperature blend control NG.
Replace your heater selector switch
Low coolant? Bad thermostat? Heater core airbound, plugged or restricted? Water pump not circulating coolant?
It could be a blocked heater core if your fan works... Or it could be your thermostat... I have an 03 that is doing the same thing. I just replaced the thermostat and it is still doing it. There is a site called BlazerForum.com you may get some better answers there
Under dash, near firewall, passenger side.
Thermostat housing on 94 will be on top of the engine right side between air filter and oil cap, not oil dipstick
Assuming the blower motor is working, it could be low on coolant, a stuck open thermostat, a plugged heater core or a faulty temp blend door actuator.
Run a new one from the blower motor body to ground

this model does not have a heater control valve, it has a specail thermostat that controls flow.

Leak in heater core
The gas tank on a 1990 Chevy Corsica is 15.6 gallons. A 1990 Chevy Corsica takes unleaded gas not premium.
I was just browsing online for Chevy Corsica heater core and found they were being sold for $53 at 1aauto.com plus free shipping. It looks like a decent deal to me and the suppliers seem pretty competent in the aftermarket auto parts business. You can check out their website for more details.
The heater core is plugged. The thermostat is stuck closed. Antifreeze/coolant level is low. The water pump is not working properly. Check the cheapest things first. Check fluid levels. See if the fluid is circulating well. If okay, replace thermostat. If still cold replace heater core.
Check coolant level .Then thermostat . Then hearter core
follow the upper radiator hose, that should lead you to it.
The outlet from the 350 engine to feed the heater core would be the one closest to the thermostat.
Your heater relay switch may be bad
