My first thought is that the R side isn't working, so the thermostat stays cool and the (working) L side gets no cooling because the (cool) thermostat has the cooling air shut off. But you didn't mention a lack of power. Is the power and engine smoothness okay? Check the various air cooling ducts. Is everything there? Do you have a mouse nest on the L side that is blocking the air flow there? This sounds like a problem that you really need to fix before you do serious harm to the engine.
