Make an appointment with stevebfl to get this fixed at his shop. I know it's across the state from you in Gainesville but, believe me, you don't want just anyone working on this A/C system. I spent over $6000 at 4 different shops in two years on my 87 300e and nobody ever got it right. The A/C in this car can be enough to make you sell it and get something else, which is why I have the VW.
