System Check - Electronic A/C

System Check:

This procedure provides an overall check of the Air Conditioning System. All of the tests can be performed without using tools or disassembly.

Complete the test with the engine idling and the temperature outside the car at 16°C (60°F) or higher. Set English-Metric Switch to English.

^ Note 1: When the Ignition is first turned on, the A/C system may run the Blower at low speed with air flow from the Floor Outlets. This operation will last for 15 seconds. This is done to purge the heater core of moist air to prevent the windshield from fogging. It will occur only when the A/C system program determines that the outside and inside temperatures are low enough to require it.

If the A/C system detects a fault in one of the system components, it will be indicated by a flashing EXT TEMP Indicator when the Ignition Switch is first turned on.

^ Note 2: No blower operation condition will occur for 1.5 minutes while the Air Mix Valve Actuator recalibrates. Recalibration will occur whenever the Battery, Heater and A/C Control Assembly or Air Mix Valve Actuator has been disconnected.
