WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
A/C COMPRESSOR CLUTCH RELAY ON CONDITIONS
| Ignition switch (IG2) | ON |
NOTE:
A/C compressor clutch relay is de-energized when any one switch, sensor or control unit shown on the left turns off.
NOTE:
The *marked device measures the temperature of the outlet air, and according to the control characteristics of the A/C compressor clutch for the compressor, the automatic compressor controller outputs the "HI" signal (12V). When air of 5°C (41.0°F) or less blows out of the evaporator, the compressor A/C compressor clutch will be turned off.
