Air Conditioner Control: Description
WARNING: This page is about a different car, the 2004 Nissan Titan. However, it is still accessible from the selected car via links, so may be relevant.
The front air control provides regulation of the vehicle's interior temperature. The system is based on the position of the front air controls temperature switch, mode switch, front blower switch, A/C switch, and recirculation switch positions selected by the driver. This is done by utilizing a microcomputer, also referred to as the front air control, which receives input signals from the following two sensors:
- Intake sensor
- PBR (Position Balanced Resistor).
The front air control then sends outputs to the defroster door motor, mode door motor, air mix door motor, and intake door motor, as necessary to control:
- Outlet air volume
- Air temperature
- Air distribution
