Where is the Buick Regal outdoor temperature sensor located?

In front of the condenser. Below is a detailed introduction to the components of the car air conditioning system: 1. Air conditioning pressure sensor: Usually installed after the dryer, it is used to detect the hydraulic pressure of the liquid refrigerant flowing through the expansion valve. Three wires: detect high pressure and low pressure. When a car collision results in refrigerant leakage and compressor oil loss, to prevent compressor damage due to lack of oil, the compressor power is quickly cut off once low pressure is detected. When high pressure is detected, the compressor power needs to be reduced to avoid wasted work. 2. Air conditioning temperature sensor: Usually installed inside the temperature sensing bulb, it is the evaporator temperature sensor. When cooling reaches a certain level, the compressor needs to be shut down to prevent frost formation, which could eventually lead to ice blockage.
