Heys guys, last month when I had the AC checked on my 89 420 because it was not cooling like it had been, the local shop guy said the freon was fine, the only thing he said he noticed was not up to parr was the fan clutch was spinning too long after the engine stopped. He said replaceing the fan clutch would help.

I replaced it two days ago and my wife says the AC is now 100% better, and I did not tell her what the shop guy said, She thinks I'm great.
