Car: 2010 Mazda 3 2.5L Manual
My car's outside temperature display is way off. It is showing warmer than the actual temperature. For example: Today the real temperature was -9C and it showed +18C.
User manual for the car says the following: Under the following conditions, the ambient temperature display may differ from the actual ambient temperature depending on the surroundings and vehicle conditions:
- Significantly cold or hot temperatures.
- Sudden changes in ambient temperature.
- The vehicle is parked.
- The vehicle is driven at low speeds.
so the question is; whether the outside temperature sensor is tied to HVAC system of the car?
I don't really care about this as long as it doesn't affect the HVAC system. I don't notice any issue with the HVAC system right now. However if it does affect heating/cooling, I will try to locate the sensor and clean/replace it.
EDIT: My car does have automatic climate control. There are two conflicting answers. One saying it does not affect the climate control system and one stating it does. Does anyone have a source to confirm this? It is also possible this is different from one car to a another.
