'87 300D Turbo, A/C problem
The R-12 A/C Freon was leaking somewhere. We finally realized that the Freon pressure switch which controls the fan operation in front of the radiator was not working. We replaced this switch a couple of years ago and have not added any Freon since. The A/C is working again perfectly.
