I have a 98 svt contour and my ac just stopped working. So before i do anything else im going to try and replace the freon or just refill it since i've never done it in the 2yrs of ownin the car. I need to know what to buy, it usually comes in like a can and it has a tube with a adaptor that u just plug into one of the ac lines somewhere.. i just u just turn on the ac and plug it in so to speek... well where is the spot where i just plug the freon into??? n what freon should i buy???
