A/C doesnt blow cold air, green light on thermostat just blinks on 2002 Mitsubishi Eclipse

When I push the a/c button, I can hear the fans turn for about 5 seconds and then they shut off and the light on the a/c just blinks on and off. Sometimes the a/c will work for a while (usually happens when the car is first started or if I'm driving on the interstate) but then shuts off and continues to blow warm air. Any help or advice would be greatly appreciated

check a/c belt tension or worn out belt if the belt slips on the compressor it will shut down and cause the green a/c light to kep flashing untill u shut off the engine and restart.
