Sometimes this port is on the oblong can called an accumulator. If not, very close to the accumulator will be a port on a small A/C line.
For a while, the wiring loom mounted to the Firewall above the A/C accumulater. Nearby and above are the starter cables intersecting the starter relay on the passengers side of the Firewall.
Sometimes removing the wiring bracket will give you better access for the port below it.

Tip

Air conditioning


When an vehicle's air conditioning system has not been used for several months, the seals within the system start getting dry. I've never worked on a Peugeot 206 or any other peugeot before, that's why I had no idea where the low pressure ac port was. The high pressure ac port is the easiest to locate, because it is in the engine compartment, facing the car from the front, on left side of the radiator. The low pressure ac port is in the engine compartment, facing the car from the front, to the back in the center, under the windshield. The low pressure ac port and the high pressure ac port both have black dust caps. The low pressure ac port is the smaller of the two.

Look back on the firewall for the two a/c lines. One is large and on is much smaller. The larger line is the low pressure line. Follow that line back to the compressor. The low pressure port will be on that line.

AC Low Pressure location on 2004 Chevy Suburban


You find the AC low pressure at the top of the compressor, orientated toward you , facing the front of the vehicle. You can also follow the compressor line to reach the port.

The valve is covered a plastic cap covering it.
Near the compressor you find two ports, the high port and low port.

To find out which one is the low port, run the air conditioner for a couple of minutes withthe engine on.
Then turn off the care and touch the lines from compressor to the two ports covered with plastic caps. Only one of the pipes will be cold, the cold line will lead you to the low port.

Regards.

Where do I recharge ac at


there are 2 ports one for low pressure and one for high pressure. the low pressure is bigger in diameter and is usually close to the dryer and or fender and firewall. the high pressure is near the condensor on the fron of the vehicle. if there are caps for the ports low will be blue and high will be red. low side pressure should be 35-50 psi and high pressure should be 135-150 psi

Your service port will always be in the larger line of the two .. which is low pressure side. It might be in the dryer also which is low side.. your dryer is about 3 inches across and 8 inches long and also has your pressure switch for the AC compressor in it.. holler if you dont find it now... thanks Jerry
