Where is the low pressure side ac port on 1984 Pontiac fiero?

The low-pressure AC port on a 1984 Pontiac Fiero is typically located on the dryer/accumulator. The dryer/accumulator is usually found near the firewall, on the passenger side of the engine compartment. It's a cylindrical canister, and the low-pressure port will be a smaller fitting compared to the high-pressure port. Look for a service port with a smaller diameter fitting and often capped with a blue cap.

However, be absolutely certain before attempting any AC work:

* Consult your Fiero's repair manual: This is the best source of information specific to your vehicle's AC system.

* Use caution: AC systems contain refrigerant under pressure, which can cause serious injury if mishandled. If you are not experienced with automotive AC systems, it's best to have a qualified mechanic perform any service or repairs.

Always prioritize safety when working with automotive AC systems.
