The thermostat on your 96 blazer goes to 240 then to 180 it blows cold air then hot why?

It's worn and sticking, once it gets hot enough it breaks loose and opens then it sticks again until it gets so cool that it breaks loose again, closes and lets the engine warm up. Replace the thermostat before you overheat and cause severe engine problems.
