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 Control Assembly (EMTC Module)
The climate control assembly integrates the temperature control, airflow mode selection, A/C request button, recirculated air request button and rear defog switch into a single unit.
The temperature control setting determines air temperature. Movement of the temperature control from COOL (blue) to WARM (red) causes a corresponding movement of the temperature blend door and determines the air discharge temperature that the air distribution system will maintain. The temperature control switch is an integral part of the climate control assembly and cannot be installed separately.
The airflow mode setting determines discharge air location. Movement of the mode selector causes a corresponding movement of the airflow mode door actuators. The mode selector is an integral part of the climate control assembly and cannot be installed separately.
The A/C request button determines A/C compressor operation, except when the mode selector is in the OFF, MAX or DEFROST mode. The A/C request button is an integral part of the climate control assembly and cannot be installed separately.
The recirculated air request button determines air inlet source, except when the airflow mode selector is in the OFF, MAX or DEFROST mode. The recirculated air request button is an integral part of the climate control assembly and cannot be installed separately.
The rear defog button signals activation of the heated backlight and heated mirrors. The rear defog button is an integral part of the manual climate control assembly and cannot be installed separately.
The EMTC module is not equipped with self-test capabilities.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
