you could have a leak anywhere in your system... the most common places are in the condensor (in front of radiator... looks like a thin radiator under the hood near the front grille), the evaporator, or the valves. take the caps off of your valves and check for a neon-green colored fluid... if there is some under a cap DO NOT TOUCH IT!!!! that is your refrigerant and it will do bad things to your skin. put the cap back on and take it to the local shop... they will have to evacuate the system, replace the valve and re-fill the system. other than that easy fix, if you hit anyting, you are looking at probably replacing your condesor at the least, plus any associated Plumbing and hardware. if you hit something, warranty woudl NOT cover it. if it was a valve, and your car is still covered, warranty should cover it, as this is a manufactuer defect.
