The low pressure side of the ac system is the ac hose that runs from the inside of the vehicle to the ac compressor. The high pressure side runs from the ac compressor to the condensor in front of the radiator. Follow the ac hose from the compressor back to the body and you will find the charge fitting. It is smaller in diameter than the high pressure side. You would need a different adapter to hook up to the high side.
The low side ac port is the line to charge in. the low side has a different size connection from the high side to prevent using the wrong port.
No, auto batteries are DC not AC.
The low pressure (vacuum) side.
Low side service port should be next to or around the left front or passenger strut tower. Or around the filter drier.
From the same port you would charge the front ac this is under the hood on passenger side of vehicle. John
You can buy a charge kit from your local auto parts store and follow directions but if it needs a charge it must have a leak. Have the leak repaired first. This is best done by a garage that does AC work.
Buiy a kit at Wal-Mart or auto parts, comes with instructions
Yes, through the schrader valve.
near the firewall on the passenger side
It should hook on the small hose or what they call the low side. Some in that year have hook up on dyer.
