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.
Steering Wheel Controls
Temperature and fan speed are adjustable from control switches on the steering wheel. When either function is selected, AUTO mode is disabled and manual control is activated. Power to the steering wheel controls is delivered from the Dash Integration Module (DIM), through the instrument panel fuse box and air bag clockspring. When the temperature or fan control switch is moved up or down, voltage is sent through a series of resistors. Varied voltage is sent through air bag clockspring to the dash integration module. Once the signal is received at the DIM, information is sent to the Instrument Panel Module (IPM) where the Air Temperature Actuator or fan speed is adjusted.
