A/c pressures

In case you’re reading this today like I am, maybe this will help. In my experience, most trucks take 36-48 oz. of freon. The gauge reading should be 30-40 on the low (blue) side and double the outside temp on the high (red) side. Air out of the vents should be 38-42 degrees if all else is good. Good luck.
