on the large ref line (suction line)
To refill freon in an AC system, you will need to locate the service valves on the unit. Connect a refrigerant gauge to the low-pressure service valve. Slowly add freon until the pressure reaches the recommended level. Be sure to follow safety guidelines and regulations when handling freon.
Freon may need to be added when the ac is not blowing cold enough. A Freon gauge can tell you for sure if the pressure is low.
The Freon is added through the low side ac port. Using the proper type of Freon and a gauge, fill the system to the recommended pressure.
Use a freon gauge and freon refill can. Connect the gauge to the low pressure ac port of the 2003 Stratus. With the engine running and ac on high, fill the system until the gauge shows full.
Freon is added through the low side ac port. A gauge is recommended to check the Freon pressure, as too low or too high pressure can cause the ac not to work properly.
The larger hose is low pressure
When recharging your AC you should first inspect your ac lines for leaks. Remove the cap from the low pressure side service port, and look at the connectors on the air conditioner lines. Remove the cap from the Low Pressure Side service port. Locate the connectors and connect the refill hose. Open the valve on the refill hose and fill.
Low Freon - Your AC system has a leak .The low pressure switch is working.
Check the Freon pressure first. The AC compressor will not turn on if the Freon pressure is too low.
Check the low and high pressure switches, the AC fuse, and relay. Any of these can cause the AC to not get power to the clutch as if the freon is too low.
The ac is recharged through the low side ac port. Using the right type of Freon and the proper gauge for that type of Freon, connect the Freon to the port and fill to the proper gauge reading. Check the can for exact refill directions.
Freon is added in the low pressure port of the ac system. It is under the hood close to the ac drier.
