Air Conditioner Control: Description
WARNING: This page is about a different car, the 2006 Nissan Titan. However, it is still accessible from the selected car via links, so may be relevant.
The front air control provides automatic regulation of the vehicle's interior temperature. The system is based on the driver's and passenger's selected "set temperature", regardless of the outside temperature changes. This is done by utilizing a microcomputer, also referred to as the front air control, which receives input signals from the following seven sensors:
- Ambient sensor
- In-vehicle sensor
- Intake sensor
- Optical sensor (one sensor for driver and passenger side)
- PBR (Position Balanced Resistor) built into the mode door motor, air mix door motors, and defroster door motor.
- Vehicle speed sensor
- Engine coolant temperature
The front air control uses these signals (including the set temperature) to automatically control:
- Outlet air volume
- Air temperature
- Air distribution
The front air control is used to select:
- Outlet air volume
- Air temperature/distribution
