ok, so I bought a can of the charging fluid for my A/C. A few years back, when doing some modifications, somehow one of the A/C lines got accidentally cut so all of the fluid ran out of the system... since then, I've replaced the line. I tried charging it over the weekend, but as soon as I hook up the can, the meter shows that it's full... I tried pushing on the button to put some in, but it just shows red on the meter. I turned the A/C on MAX but that made no differnce.
This is on a '97 Camaro.
What am I doing wrong?
