AC wont stay on Help!, Help! Options

[thatSt204guy]

So the problem is, when i turn on my AC is only stays for about 3 seconds and then it just shuts off. I can feel it blowing cold air and I just replaced the AC relay, so could it be a problem with the compressor or some kind of sensor??

Forgot to mention that the light also blinks off and on before it shuts down.

Any help is appreciated!

Oddly enough, mine started doing the same thing a couple of days later.
It would work for a few minutes and then it would go off and the light on the AC switch would be blinking.

But a couple of days later it will stay on the whole ride home. The only difference is that it wasn't very warm the other day when it was acting up and now it's kinda hot out.
I haven't had time to fully investigate it but I have noticed, even when it continues to run the compressor is short cycling. Which to me indicates that it's short on refrigerant However I also realized that it may need a bit of compressor oil.
The oil for the compressor is added to the refrigeration system just like the refrigerant, it circulates through the system with the refrigerant.
For a full charge you need a little 8oz can which you can add yourself with buying just a small hose with the valve and fitting on it.
If you don't have enough compressor oil in the system the compressor may chatter or make other noises and could seize up. maybe if it gets jammed and can't turn that is when the light starts blinking?

I've got two more weeks before finals and then I'll have some more time to look into it.
