Where is the ac low pressure port on 2002 rendezvous?

On a 2002 Buick Rendezvous, the AC low-pressure port is typically located on the passenger side of the engine bay. It's near the firewall, on the accumulator, and is usually marked with a blue cap. To identify it easily, look for the smaller of the two AC service ports. Always ensure the engine is off and the AC system is not under pressure before attempting to service it.
