Electronic Automatic Temperature Control

Climate Control Assembly
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.

Steering Wheel Audio/Climate Control Switch
The steering wheel audio/climate control switch, located on the right side of the steering wheel, allows the driver to adjust the passenger compartment temperature setting and manually override the blower motor speed setting. For removal and installation of the steering wheel audio/climate control switch, refer to Radio, Stereo, and Compact Disc.
