Code B1009 RAM Description

The HVAC A/C Heater Control contains various switches and knobs that are used to change the systems operation. There are currently three types of switches used depending on the configuration of the system. Push button momentary switches which are normally open or in the Off position. Multifunction or rotary switches which have several distinct positions and potentiometers which are a rotary variable resistor that is used for a more precise control. An active Diagnostic Trouble Code (DTC) indicates that either a control switch or potentiometer is stuck in an On position or out of a calibrated range. A stored DTC indicates that control switch or potentiometer was stuck On or out of calibration but has since returned to its normal state.
