On the line right at the compressor.
The 1999 Ford Ranger low pressure air conditioning valve can be found on the air conditioning compressor. The low pressure valve will be labeled as the low pressure port.
The LDC sensor on a 1999 Honda CR-V refers to the "Low-Pressure A/C Switch" or "Low Pressure Cut-Off Switch," which is part of the vehicle's air conditioning system. It monitors the refrigerant pressure and helps protect the A/C compressor from damage by shutting off the system if the pressure is too low. This sensor is crucial for maintaining the efficiency and longevity of the air conditioning system. If it fails, it can lead to poor A/C performance or system failure.
BEHIND THE COMPRESER
Your 1999 Oldsmobile air conditioning air compressor can be found on the left-hand side of the engine. You can fill the system with Freon through the low pressure port.
The expansion valve on a 1999 Saturn SC1 is located in the engine compartment, typically found near the evaporator core inside the dashboard. To access it, you may need to remove the dash or certain components to reach the area where the air conditioning system connects to the evaporator. It's important to ensure the AC system is properly discharged before attempting any repairs or replacements.
You can charge your 1999 Mercury air conditioning system from the low pressure port on the air conditioning compressor. Connect your Freon bottle to the low pressure port and release the Freon into the system.
This is for the air conditioning system
The system has pressure on it but the switch can be screwed off. A schrader valve prevents the loss of refrigerant. Install the new one after you have put some Air conditioning oil on the O ring seal.
The Freon is added through the low side ac port. A pressure gauge is used to show when the system is full. Follow the Freon can directions closely.
the low side is located behind the engine by the fire wall to the passager side should have a green or ble cap on it
