Climate Control Assembly: Notes

The electronic automatic temperature control (EATC) module, located in the instrument panel, has the following features:

• A blower speed override control for manual input.
• A vacuum fluorescent display for displaying set temperature, ambient temperature, function and diagnostic trouble codes (DTCs).
• An On-Board Diagnostic (OBD) feature to supply the technician with diagnostic trouble codes (DTCs). These DTCs direct the technician to the inoperative component.
