Cold Purge

In cold purge, the blower powers low. The air flow is directed to the front defrost outlets. This keeps the breath humidity off of the windshield. Normal operation resumes several seconds after one of the following conditions exist:
^ The program number would result in cooling.
^ The coolant temperature is above 36°C (97°F).

If neither of these conditions exist within approximately 1-4 minutes (depending upon the ambient temperature), the heater and A/C programmer automatically resumes normal operation.
