Re: Whistling or hissing type noise in AC vent when compressor clutch activates
I attempted to recharge the system. But the gauge shows 0 PSI when the car is turned on, with the AC on full blast. When the car ignition is off, the pressure gauge shows at about 40 PSI, in the green. I decided to make a dumb move, to want to fill to 50 PSI to the max where it shows in the green. ...

Re: Full charge after only half the freon?
About 30 ounces of R-134a does seem a little light. I think it should be around 32-38 ounces based on the R-12 spec. Did you weigh-in the charge or estimate using the small cans?

Re: New compressor hard to turn by hand
Next time buy from Tim at Arizona Mobile Air !!!
I've bought at least three compressors and an evaporator from Arizona Mobile Air for various vehicles over the past 2.5 decades. And I bought a vacuum pump from them for my work laboratory.
