Temperature Increase/Decrease Rocker Button
WARNING: This page is about a different car, the 1998 Pontiac Bonneville. However, it is still accessible from the selected car via links, so may be relevant.
With system in any mode except OFF and preset temperature 66-84°F (19-29°C), pressing increase/decrease end of rocker button once will change preset temperature one degree. If decrease end of button is pressed with preset temperature at 65°F (18°C), preset temperature will change to 60°F (16°C). If increase end of button is pressed with preset temperature at 85°F (29°C), preset temperature will change to 90°F (32°C).
An increase or decrease in preset temperature signals A/C-heater programmer to change blower speed, air outlet location, and outlet temperature. Programmer will continue changes until sensors indicate preset temperature has been reached. With system OFF, pressing either end of temperature rocker button will activate AUTO mode.
