Ok so yesterday The Girlfriend was sitting in traffic and the A/C started to blow Hot air. SO today I go out and look at the car to check the a/c pressure. Upon pulling the cap off the low pressure side to find a gaping hole blowing air out of it. So my question is Has any body ever seen a A/C system Eat a Schrader(sp) Valve? and how hard would it be to replace the valve.
