To recharge the air conditioner on a 1989 Plymouth Colt, locate the low-pressure service port, which is typically found on the larger diameter aluminum line connecting the evaporator to the compressor. The high-pressure service port is on the smaller diameter line. Use a refrigerant recharge kit to connect to the low port, following the manufacturer's instructions for adding refrigerant. Always wear safety goggles and gloves, and ensure the engine is running with the A/C on during the recharging process.
