Default 1993 Honda Accord heat doesn't work.....?

It blows air just no heat, I don't have a place to pour antifreeze in and when I take the radiator cap off it is full. Any suggestions?

check the water valve, its in the engine compartment along the firewall, it has a cable going to it from inside the car, sometimes the valve inside it brakes and wont move even though the arm on the outside is moving, easiest way to check is to watch the screw on the side of it to see if it is turning with the arm. could also have a clogged heater core, if the valve is working, feel the inlet and outlet heater hose, they should both be very hot, if one is luke warm or cold, your heater core is clogged.

also make sure the car is getting to operating temperature, is the gauge needle going close to the middle, if not it might have a stuck open thermostat

hope this helps

you should have your heater core flushed out.
