I have a 2015 Mazda 3 (A.T / 85,993K mi) with my a/c not blowing cold air (but air is still blowing). The a/c clutch isn't engaging, system is full of refrigerant, heater is working (fans working), I found I have a very small leak on the condenser, the fuses and relay are all good nothing is blown BUT they are not receiving any power. What should my next steps be? 🙁
either AC needs recharge, or it could be the temperature blend door
If only the fuses and relays related to the AC system do not get power, you should check the BCM. Odds are that you may need a new one.
If the A/C clutch is not engaging when there is sufficient refrigerant in the system your low-pressure cutoff switch (or the wiring to it) may be bad. Typically they will cut off the compressor when system pressure drops below around 20 psi.
