O.K. I will get a second opinion to check for a leak. By the way, when the a/c was fully charged it did not really get cold it just got cool. Should a 85' get cold?. My wife's 300e is a 93' and it gets freezing cold. If there is a leak then what? I will do whatever it takes to get my a/c cold. I just don't want to keep wasting money. Thanks for the advice.
