Detailed Product Description

The Dorman 904-611 HVAC Pressure Switch is a critical component in the air conditioning system, designed to monitor refrigerant pressure and protect the system from damage due to abnormal pressure levels. This switch operates on a 5-volt electrical system and is rated for 1 amp, making it compatible with the electrical requirements of many BMW, Mini, and Rolls-Royce vehicles. It is specifically engineered for use with R134a refrigerant, which is standard in modern automotive A/C systems.

The switch activates at a pressure limit of 260 psi (closed) and deactivates at 475 psi (open), with a maximum pressure tolerance of 522 psi. Its metal housing provides durability and resistance to harsh under-hood conditions. The connector is black, rectangular, and female, designed to mate with male pin terminals, ensuring a secure and reliable electrical connection. The bolt mount type allows for straightforward installation in the designated mounting location.

Compatible Vehicles and Applications

This HVAC pressure switch is compatible with a wide range of BMW models including the 128i, 135i, 228i, 320i, 328i, 330i, 335i, 535i, 740i, M3, M5, X3, X5, and Z4, among others. It also fits Mini models such as Cooper, Cooper Clubman, and Cooper Countryman, as well as Rolls-Royce models like Phantom, Ghost, and Wraith. The Dorman 904-611 is designed for specific fitment, ensuring proper function and integration within these vehicles' HVAC systems.

Common Issues Addressed by the HVAC Pressure Switch

  • Prevents compressor damage caused by excessively high or low refrigerant pressure
  • Helps maintain optimal air conditioning system performance
  • Protects against system shutdowns due to pressure irregularities
  • Ensures accurate pressure monitoring for efficient climate control
  • Reduces risk of refrigerant leaks by maintaining system integrity

Installation Notes and Tips

  • Verify vehicle compatibility using the part number 904-611 before installation
  • Ensure the system is depressurized and the ignition is off prior to replacement
  • Use appropriate tools to remove the old pressure switch and install the new one securely with the bolt mount
  • Check the connector for proper engagement and secure fit with the male pin terminals
  • After installation, test the A/C system to confirm correct operation of the pressure switch
