How do you recharge the air con on mk 4 astra?

To recharge the air conditioning on a Mk 4 Astra, first, locate the low-pressure service port, usually found near the condenser or the compressor. Next, connect a refrigerant recharge kit to this port, ensuring the kit is compatible with your vehicle's refrigerant type (typically R134a).
