How can you reach the refill port of 2003 malibu air conditioner?

The 2003 Malibu does not have a refill port for the air conditioning system. R12 refrigerant was banned from production in the United States in 1996, and the 2003 Malibu uses R134a refrigerant. Cars built for use with R134a refrigerant do not have refill ports. In addition, tampering with automotive AC systems can be dangerous due to the high pressures involved in the system. To add or remove refrigerant from a 2003 Malihu, you will need to take the car to a certified technician.
