- Ambient temperature
- Air conditioning system's efficiency
- Fan speed
- Desired cabin temperature
In general, the air coming out of the vents should feel cool and refreshing. However, the exact temperature can vary. On a hot day, the air coming out of the vents may be cooler than on a mild day. Additionally, if the air conditioning system is not working properly or the fan speed is too low, the air may not be as cold as desired.
As a rough guide, the air coming out of the vents with the air conditioner on should be around 15-20°C (59-68°F). However, this can vary depending on personal preferences and the specific conditions in the car.
