On my 1989 379 the ac is not working right
On idle it blows 50° from the outlet and the compressor not cycling
Engine fan is working
I put 5 pounds of freon to it
Can it still be low on freon
It use to blow about 30° from the outlets before I had to replace some orings and hose
A/C problem

5lbs is probably to much. I have a 94 and it calls for 3.63lbs.
Roger McG Thanks this. -
