Where is the high side ac port on an 88 Chevy beretta?

The high-side AC port on a 1988 Chevy Beretta is located on the compressor. It's usually a thicker, larger fitting compared to the low-side port. You'll find it near the compressor's connection to the AC lines. However, without being able to see the specific setup of your car's AC system, precise location on the compressor itself will vary slightly. It's best to consult a repair manual or diagram specific to your vehicle's year and model to be certain. Improperly identifying the ports can lead to damage to your AC system.
