Temperature Control

Individual temperature control is provided driver and passenger by means of one damper motor and one cam wheel controlling 2 linkages. ECC control module computes temperature control damper motor position based on inputs from temperature dial settings, passenger compartment temperature sensor, solar sensor, engine coolant temperature sensor and outside (ambient) temperature sensor.

The difference between the desired and actual interior temperature, as monitored by passenger compartment temperature sensor, has a direct effect on temperature control damper positions.

In direct sunlight, the temperature control dampers are positioned to provide a lower temperature, as determined by solar sensor input. If the engine is cold and outside temperature is low, the temperature control dampers are set for more heat to reach the desired temperature faster.
