Re: 98 Suburban 2WD/5.7L AC Issue - HELP

First question is what does the label tell you it holds TOTAL? By my calc you put in 4.5 pounds.

Second what pressures are you actually reading?

Third there is a screw adjustment in the switch located in the accumulator. It's located between the terminals. Flat head.
