Just follow the A/C lines, the one with the big line is the Low side and the one with the small line is the High side. The High side is usually near the receiver dryer near the condenser. The Low is some where in the engine compartment. Lol. Give us a picture of the engine. Maybe we can help.

Thanks for every one's help. I found the low Pressure port next to the oil filter.

Easy job.

Buy a 134a ref can with an adapter and pressure gauge. Auto part store can guide you.

Start engine, run AC full blast with Windows down .

Find the L pressure port next to oil filter, remove cap. Attach the adapter to it. Measure ref pressure. If pressure is in green zone, no need to add. If in red zone, open the can , shake it up and screw it in the adapter. Hold can upside down, Squeeze trigger to pump ref into low pressure port. Stop when pressure reaches green zone. Close cap.
