Where is the lowside port on a 2000 bravada?

On a 2000 Oldsmobile Bravada, the low-side port for the air conditioning system is typically located on the larger diameter A/C line, which runs from the evaporator to the compressor. It is usually found near the firewall on the passenger side of the engine bay. The port is often capped with a plastic cover and can be identified by its smaller size compared to the high-side port. Always ensure the engine is off and the system is depressurized before attempting any service.
