Where is the low side service port on a 2002 Saturn SL1?

On a 2002 Saturn SL1, the low side service port for the air conditioning system is located on the accumulator, which is situated on the passenger side of the engine compartment, near the firewall. The port is typically marked with a blue cap and is smaller than the high side service port. To service the system, ensure the engine is off and the AC is not running before connecting any gauges or refrigerant.
