Where do you recharge the air conditioning on a 1999 mercury mystique?

To recharge the air conditioning on a 1999 Mercury Mystique, locate the low-pressure service port, which is typically found on the larger diameter A/C line, usually near the accumulator or firewall. Remove the cap from the port, connect the refrigerant recharge kit, and follow the instructions on the can to add refrigerant. Make sure to monitor the system pressure and avoid overfilling. Always wear safety gear and ensure the engine is running with the A/C set to the maximum cool setting during the recharge process.
