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.
