IT helps to monitor high side pressure when trying to characterize a malfunctioning system.

My guess is that maybe your orifice valve is blocked or just frozen (did you ever charge from empty without doing a vacuum first?).

Could also just be the heater control valve stuck and having coolant go through the heater core, heating up the air.

The low side pressure does not seem that bad but you can;t tell much without having a high side pressure reading. Careful - overcharging a system with r134 is easy and will cause poor performance. Compressor should likely cycle on 50% of the time (estimate) to indicate a proper charge.

Might be time for a new accumulator and new OV or VOV. Then a good deep vacuum and recharge.

Good luck,
