What you are wanting to add is R134a Freon. The port that you are talking about looks like the same connection that is on your tires. It is called a Schrader valve. They have a cap on them like a tire valve stem. They are located on the air conditioner lines that lead to and from the compressor to the cabin. They are different sizes and if you are not familiar with them, find someone that is because you can get hurt or damage your a/c if you make a mistake.
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.
Not enough info.with the compressor running and the charge line on the low pressure service port( the big line)it should charge. Be sure the compressor is running. If it's not: There is a low pressure switch in the big line. to check it disconnect the 2 wire connector, use a paper clip to jump between the 2 wires. If the compressor runs either the switch is bad or the pressure is not getting into the system at the fill port
The people who answer questions on this website do it for free. We have some books, but not an entire library of every book known to man. My standard answer to this question is - there are two ports on the ac lines or the compressor with plastic caps. One is bigger than the other to help prevent you from hooking up to the wrong side of the compressor. That's the best I can do since I can't see your car.
Hi, determine if your car uses R134 or R12 refrigerant. You will notice screw type connectors on the both the High Pressure Side and Low Pressure Side lines in models using R12 refrigerant. R134 compatible models have quick connect valves on both sides. Models made before 1995 may use the old R12 refrigerant. If this is the case, you must have your Chrysler's air conditioning system retrofitted to use R134 refrigerant. Mixing R12 and R134 refrigerants is dangerous and may cause damage to your vehicle.
Check your air conditioning system pressure using an automotive air conditioning pressure gauge. Keep in mind that in order to get an accurate reading, the air conditioner has be turned on the coldest setting with maximum blowing power.
Remove the Low Pressure Side port valve cap and set it aside. The location of the port varies, but it is usually in front of the engine block. Attach the refill hose to the port on the Low Pressure Side of the air conditioning system. The Low Pressure Side port is smaller the High Pressure Side port. Because the ports are different sizes, the refill kit hose should fit only on the Low Pressure Side port. Additionally, the High Pressure Side port will usually have a red cap or be marked with an H or the word High
Allow the air conditioner to **** the refrigerant out of the can by slowly turning the valve on the refill kit hose. Pay attention to the way you hold the can. Most kits will have you hold the can upright when you recharge the air conditioning system. It may take as long as 10 minutes to empty a single can.
Turn the valve to the off position and remove the refill hose from the port. Recap the port before closing the hood.
Let the air conditioner stay on for at least 30 minutes. This allows the refrigerant to move throughout the entire system.
sounds like the a/c is not fully charged, have the system serviced by pulling the freon out and pull a vaccum on the system and recharging with proper amount of freon. this should fix the problem. if when fully charged and this happens either the high pressure switch or low pressure switch could be bad.
In order to charge, you must locate the low pressure valve to install the refrigerant. The low pressure valve is between the compressor and the evaporator. Do not charge on the High Pressure side, The high pressure valve is between the compressor and the condenser. To locate the low pressure valve, follow the line that comes from the compressor and routes toward the firewall. The valve will be somewhere on that line. Do not overcharge. The amount of pressure that is needed on the low pressure side will depend on the ambient outside temperature.
Sounds like the A/C system just needs to be recharged. When was the last time you had this done? Just take it in to your mechanic and he can do it for you and if that's not it for some reason, then he will be able to find the problem but most likely you need more freon added.
