95 chevy blazer overheating

my blazer runs fine, but when i turn on the ac and drive for a while, once i stop and turn off the car it will not turn on again if tried. the temp gauge reads high as in overheating. so once i let the car cool down it will turn on again. it also runs rough with ac on. please help what should i do:confused:

Describe not turn on again?

Have you checked coolant level in rad?
Is the fan clutch woring good?
How is the thermostat?
How hot is it actually getting.
Like over 220-230 or boing over?

the engine will turn but not start completely. i have checked coolant its good, and it heats up over 220, i have not checked thermostat and fan clutch i will check and reply, why would this happen only when ac is in use?

Ac puts more load on and build more heat in the coolant system.
