2000 S70, the air conditioner is fully charged. If outside teperatures are below 80 degrees, it cools great. Air coming out of vents is about 40 degrees. When the outside temperature are in the 80's or above the a/c will cool for about 3 to 4 minutes then quit. If I turn the a/c off for about a minute, it will cool for 3 to 4 minutes then stop again. anyone ever have a problem like this for know how to fix it?
