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.
EMTC Module (Climate Control Assembly)
The climate control assembly integrates the temperature control, mode function selection, A/C request button, recirculated air request button and rear defog button into a single unit.
The temperature control switch setting determines air temperature. Movement of the temperature knob 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 A/C request button determines A/C compressor operation, except when the function selected is OFF, MAX A/C, DEFROST or FLOOR/DEFROST. The A/C request button is an integral part of the climate control assembly and cannot be installed separately.
The recirculated air request button can select recirculated air in any mode except MAX A/C, OFF or DEFROST.
The rear defog button (if equipped) signals activation of the heated backlight and heated exterior rear view mirrors. The rear defog button is an integral part of the climate control assembly and cannot be installed separately.
The heated mirror button (if equipped) signals activation of the heated exterior rear view mirrors. The heated mirror button is an integral part of the climate control assembly and cannot be installed separately.
The EMTC module is not equipped with self-test capabilities.
