Heater linkage won’t stay open

The heater control pulls against a spring at the heater box. the spring is trying to pull the control closed. The CTLS without injection have a block that the cabin and carb heat go through. inside that block is a spring and a couple scrubbers that put friction on the two control shafts. If it is pulling closed you don't need to lubricate the cable. If you have lubricated the shafts behind the knobs that is your problem. A temporary fix would be to get a piece of rubber hose long enough to fill the gap between the knob and the panel. Slit the side of the hose and slip it over the shaft.
