There is a vacuum actuated control valve at the firewall on the driver side. The valve may be defective. Its default position is on (heat), so you can try to run a vacuum line directly to it to see if it pulls it closed and turns off the heat. If not, then wire the lever closed until you can replace the vacuum assembly.
