The AC in my 92 Bonneville is not cooling at all. The clutch does not engage. Fuses OK, fan working. The pressure is well into the red on the low pressure side, but the compressor in not working of course. About a month ago I charged the system after I let it finish emptying completely with R-124a which it was using before. It was leaking through the valve, I replaced it. Any idea what it may be? Thank you.
