For some reason the a/c only blows on low. When switched to medium and high it turns off. I heard it has to do with something with the a/c chip.

That's most likely a bad Blower Motor resister. It's located under the dash on the passenger side, next to the blower motor.

Also I am not sure it is the blow motor resister that is the problem. Because it stopped working when I was forcing the switch to move to the MEDIUM because it was STUCK. So now it only works on LOW

Then you're going to have to get it diagnosed professionally.

Ok. Because I know that the resistor is fine if the LOW and MEDIUM are working properly.

Don't be so sure-you must have broke the blower switch, now you need to have it troubleshoot professionally as mentioned by Doc WrenchTech
