Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Climate Units (2000): Introduction
The control panel and all switches that belong to climate control are located on the middle of the instrument panel. Three large rotary controls control fan speed, air distribution, and temperature. There are also three switches that control recirculation, electrically heated rear window, and activation of AC system (AUTO or OFF).
This system allows a mixture of passenger compartment air and fresh air through the middle air vents. For more information about this "air mix function", see: Air mixing openings
The airflow's direction can be adjusted individually for all vents on the instrument panel.
The recirculation button to the left on the control panel controls the two valves that close the fresh air inlet. This connects heater/ventilation unit with the interior. At recirculation, the air is recirculated to 100%.
The two recirculation valves only have two positions - fully open or fully closed.
The rear window's heating works via contact +15. This means that the rear window's electric heat is connected even if the engine is not running.
No time-controlled RECIRC-function.
