A/C Heater Control: Operation
WARNING: This page is about a different car, the 2004 Dodge Sprinter. However, it is still accessible from the selected car via links, so may be relevant.
To control the interior temperature, the A/C-heater control uses the actual values from the temperature sensors and the CAN bus and compares them with the nominal value of the temperature control switch. The A/C-heater control is diagnosed using a DRBIII(R) scan tool. Refer to BODY DIAGNOSTIC PROCEDURES .
The A/C-heater control cannot be adjusted or repaired and, if faulty or damaged, it must be replaced.
