I had to replace my "Condensor bottle"(I think that's what it's called). The problem was that it has a metal band around the outside to hold it in place. The combination of the 2 rusted and erroded. The small bottle unit is located at the front of the engine compartment on the drivers side. You might want to take a look at the condition of that unit. Sorry I can't edumacate ya better on the proper name. Good luck though A/C can be pricey.
