Where is the Buick Regal outdoor temperature sensor located?
2 Answers
At the lower right corner of the front windshield. Here are the relevant details: 1. Temperature: The outdoor temperature displayed by the car is accurate. For example, when the car's instrument panel shows low outdoor temperature through a snowflake symbol, it is only to alert the driver that the outside temperature is low, to be cautious of icy roads, and to drive carefully. Generally, a reminder is issued when the outside temperature drops below 4 degrees Celsius to ensure the driver is aware of external temperature changes that may not be felt inside the car. 2. Principle: The outdoor temperature sensor typically uses an NTC thermistor for measurement. NTC stands for Negative Temperature Coefficient, meaning the resistance decreases as the temperature increases.
I often tinker with my own car, especially with models like the Regal. That outside temperature sensor is usually located in the front of the car, behind the grille or inside the front bumper area. It's designed there mainly to avoid interference from engine heat and to directly contact fresh airflow, ensuring more accurate measurements. If your dashboard temperature display keeps jumping around—for example, showing hot when it's actually cold outside—it might be due to dust or small stones blocking the sensor, and it needs cleaning. My car had this issue once; I crouched at the front, reached into the grille area, and sure enough, found a bunch of dust. Wiping it off fixed the problem. The location isn’t hard to find—just look for a small probe-shaped thing when you crouch down, but don’t yank it forcefully to avoid damage. By the way, a dirty sensor doesn’t just affect the temperature display—it can also mess with your AC settings. So, take a quick look at it during regular car washes to avoid trouble.
