I have a slow leak somewhere in my AC system. The people at the AC speciality shop couldn't find the leak, so I'm in the process of replacing all three of my Schrader valves in hopes the leak is something simple and this will solve the issue for now. Below is a photo which shows the location of the three schrader valves in my '03 9-5 2.3T Wagon. I've already changed #1 and #3, but schrader valve #2 is a different story. The valve is not located on the side of the fitting as shown. I suspect that the valve is pointing down through a hold in the body work (just behind the passenger headlight) and you would probably access the valve from under the car, but I'm not sure. Do any of you have any experience getting at the schrader valve labeled #2 ?
