Blower Control
WARNING: This page is about a different car, the 1999 Cadillac Eldorado and 1999 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.
When AUTO button is selected, blower speeds are controlled automatically based on various system inputs. If up arrow is pressed once, blower speed increases slightly and control panel displays HI AUTO. Blower is still automatically controlled, but at slightly faster speeds. If up arrow is pressed twice, blower runs at a fixed high speed and control panel displays HI. This overrides automatic control. If down arrow is pressed once, blower speed decreases slightly and control panel displays AUTO LO. Blower is still automatically controlled, but at slightly slower speeds. If down arrow is pressed twice, blower runs at a fixed low speed and control panel displays LO. This overrides automatic control.
