Note: This method is specifically for third generation of Toyota Tundra made on or after 2014.


  1. With the climate control on and in auto mode, you can defog the windshield quickly by pressing the windshield defog button.
  2. The system will switch out of auto and the vents and fan speed will change to focus on the inside of the windshield.
  3. Raise the temperature. And make sure the A/C button indicator is lit to speed up the process.
  4. Press the Auto button to return to automatic operation.
  5. If the rear window or side mirrors fog up, press the rear defog switch. The light in the button will let you know when they’re turned on.
  6. Heating elements in the mirrors and the rear window will heat the glass to help remove moisture. The heaters will automatically turn off after about 15 minutes.
  7. Pressing the button again also turns the defoggers off.
