Where is the low pressure charging port for a 2000 Monte Carlo air conditioner?

The low-pressure charging port for the A/C system on a 2000 Chevrolet Monte Carlo is typically located on the dryer. The dryer is part of the A/C system and is usually found near the firewall on the passenger side (right side of the engine compartment). It's often a smaller fitting than the high-pressure port.

However, it's crucial to consult a repair manual specific to your 2000 Monte Carlo to confirm the exact location and to avoid accidentally working on the wrong port (high pressure port). Incorrectly charging the system can be dangerous and cause damage. If you're not experienced with automotive A/C systems, it's best to leave this task to a qualified mechanic.
