Compressor cycling clutch engagement/disengagement every one to two seconds and pressure at the low-pressure port bounces/fluctuates between 20–40 PSI.
A/C system was allowed to run after engine start up on the MAX cab air re-circulation setting for a minimum of three minutes prior to the pressure reading being taken. Ambient temperature was about 75° with high humidity.
Considering that the pressure at the low-pressure port bounces between 20–40 PSI, would the poor cooling/compressor cycling likely just be due to the system being low on refrigerant and in need of a charge or would it be a safe bet to expect there to be other part/electrical problems involved?
Really just would like to get an idea of if I'd be wasting my time/money buying a can of R134A and shooting it in there.
Thanks for any help/input you can provide.
