Where is low side porton2000 Chevy Malibu?

The low-side port for the A/C system on a 2000 Chevy Malibu is located on the compressor. It's typically a smaller diameter port than the high-side port. However, you should not attempt to locate or service the A/C system yourself unless you are a trained and qualified technician. Refrigerant under pressure is extremely dangerous. Improper handling can result in serious injury or death. If you need service, take your Malibu to a qualified mechanic or A/C specialist.
