When it comes to climate controls, we’re in favor of dials that are easy to use, especially in cold climates where the morning commute usually starts out with some cumbersome gloves. However, from a design perspective, big dials don’t always fit the bill. Such is the case in the 2007 Avalanche, which instead uses clearly marked buttons for temperature control, fan speed, and fan direction. Smaller buttons are provided for air recirculation, a/c, and an automatic function. A symbol represents the OFF function, though idiots like us would prefer the word OFF versus trying to figure out what the damned symbol means while driving. Call us old-school. In any case, the setup is effective and looks nice with subtle chrome accents.
