Ranger A/C

I vacuumed the Ranger's A/C system and then charged with about 25oz of R-134a. The system actually had 15 psi in it and I haven't charged it for years.
While moving, and turning the fan speed down, I saw vent temps as low as 40F which is pretty good. I then adjusted the low pressure switch screw 1/2 turn counterclockwise. It can get below 40 now. I will have to try in warmer weather to see for sure. It doesn't take much to cool the cabin anyway.
