Set the temperature to HI (auto systems) or Full Hot (manual systems).Ħ. Turn on the Quick/MAX defrost button (button has icon with Windshield and 3 squiggly arrows).ģ. When your vehicle’s windshield needs to be defogged or defrosted, following these 6 steps will help clear it more efficiently:Ģ. Your climate control system also incorporates important functions designed to help improve visibility through the front windshield and rear window in inclement weather. Note: You can’t turn off airflow to all 3 locations. If you’ve pressed multiple buttons and want to turn off airflow at one of the locations, simply press the button of the location you want shut off. They act like simple on/off buttons, so you can press an unlit button, for example, and it will light up to indicate that air is flowing to that location. You can press any or all of the 3 Airflow Control Buttons to precisely direct airflow to one or more of these areas.

Dashboard Vent (icon shows an arrow to the torso/head): The air that comes out of the dashboard vents.

Floor (icon shows an arrow to the feet/legs): Sends airflow out of the vents at the floor.

Windshield (icon shows an arrow to the windshield): Sends airflow out of the vents near the windshield.

When lit, air is directed through both the floor and windshield defrost ventsįor the GMC Sierra, a more flexible air distribution selection scheme allows you to pick a wider range of air delivery options using 3 buttons that are used in combination.

Defog: Press the button with an icon with arrows pointing to the windshield and arrow pointing to the legs and feet.

When lit, air is directed through both the floor and dashboard vents.

Bi-Level: Press the button with an icon with arrows pointing towards both the feet and torso.

Floor: Press the button showing an icon pointing towards the legs and feet, and air will be primarily routed through vents placed near the floor of your vehicle.

Vent: Press the button showing an icon pointing towards the upper torso, and air will be routed through vents on the dashboard/ instrument panel.

To select a function, simply press a button and an indicator light will come on once one of these modes is selected. You can control where that air is delivered through buttons on your dashboard.

GM and many other car makers choose the HIGH beam headlights as the DRL source to avoid burning out the filaments in the low beams.Your climate control functions by blowing heated or cooled air through a system of ducts within the vehicle’s interior.

By routing the power in series through both HIGH beam headlights, each light burns at half brightness. The DRL relay contacts close which provides battery power from the EXT LTS fuse through the right HIGH beam headlight and then through the left HIGH beam headlight before reaching ground. If those conditions are met, and the BCM determines there’s daylight, it provides ground to the control coil on the DRL relay. For the DRL system to work, the IGN must be in the RUN position, the parking brake must not be activated and the transmission must not be in PARK. Thirty seconds after you start your vehicle with the headlights off, the body control module (BCM) checks the voltage on the ambient light sensor. Here’s how that GM daytime running lights system works.

GM uses a few different daytime running light schematics, but most use a series wiring method that divides battery voltage in half through series wiring.
