What should the AC pressure be on a Mazda 3?
I am not sure if anything changed in AC between teh first and 2nd gen Mazda 3s. Looking at the factory service for first gen, the optimal pressure reading for 104F ambient is 10-19psi on the low side and 268-311psi for the high side. Are you reading normal 40-45 degrees at the passenger vent?
What should my AC low side pressure be?
When the engine is on and the AC is on high, low pressure readings should be around 30 psi and the high pressure side should be about 250 psi depending on your car. The correct reading will display once the clutch engages and the gauge stops cycling.
What does it mean when your AC pressure is on both sides?
If there are readings on both the high and low sides but they are not the correct specified pressures, it means that certain parts of the AC system are not functioning properly, such as the expansion valve, compressor, and clutch. AC pressure readings and what they mean

What should the pressure be on the low side of the AC?
The pressure reading from the low side should be between 25 and 30 psi and the high side between 200 and 250 psi. But if you see the AC low side high, high side low, such as the low side is 100 and the high side is 150, there might be problems with any of the inner components.
What should my car AC pressure be at idle?
First you will need to check the pressures at idle and record both HIGH and LOW side pressure readings. These pressures will vary depending on ambient temperature (temperature of the outside atmosphere), but ideally, you will want to see your low side pressure between 30-40 psi and your high side pressure between 150-175 psi.
