Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Air Conditioning (A/C) Refrigerant Distribution Valve (ACRDV)
The ACRDV is a PCM controlled solenoid which provides a regulated control of refrigerant flow to the passenger compartment loop. The PCM opens or closes the ACRDV based on the passenger compartment A/C request. The ACRDV is a normally closed valve, preventing the refrigerant flow. When the passenger compartment A/C is requested ON, the PCM provides a ground path to the solenoid which opens the ACRDV.
