Review on 🌡️ ACDelco GM Original Equipment 25775833 Ambient Air Temperature Sensor Assembly: High-quality with 2 Terminals and 2 Alignment Tabs for Accurate Monitoring by Cris Drew

Works great on at least 2005 Silverado, 2005 Suburban and 2004 Yukon. I replaced it as a PM as the old one looked a bit rough and the new sensor is so cheap. This is a sensor that sends temperature data to a thermometer in the rear-view mirror and is mounted between the grille and radiator, near the center on the driver's side. ** Another similar sensor is installed next to the headlight on the passenger side. This is another P/N sensor that is linked to the automatic/digital heating and air control system if your vehicle is equipped with one. If you want that, you need a different P/N sensor.
