With A/C on high and engine running the gauge fluctuates between 15 PSI and 45 PSI (max range showing R-134a level is good) every 30 seconds. Example compressor on running fans are turning gauge reads 15 PSI. Compressor off, fans not turning gauge reads 45 PSI (max R-134a level). Should I add R-134a? Do not what to overcharge system. No way of taking it out. Recharging the PSI system with AutoZone Sure Bilt PSI gauge.
