Manual Temperature Control

WARNING: This page is about a different car, the 2002 Dodge Grand Caravan, 2002 Dodge Caravan, 2002 Chrysler Voyager, and 2002 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.

The front blower speed and rear blower speed (if equipped with rear HVAC) must be set to High and the evaporator temperature sensor, must be greater than 55°F or the test will fail immediately. The test is activated by depressing the A/C and PWR buttons simultaneously and holding them depressed for no less than 5 seconds. The PWR and A/C LEDs will blink on and off until the test is complete. If the LEDs stop blinking before 2 minutes, then the cool down test has been completed successfully. If the 2 minutes expire without the expansion valve temperature reaching 20°F less than the outside air temperature, then the cool down test has been failed and further A/C system diagnosis is required. If the test is failed, the LEDs will continue to blink until the vehicle has been driven for greater than 8 miles.
