We previously covered what to do if the battery dies in your 2020 Chevrolet Corvette C8, including how to access the cabin, front trunk, and rear hatch without battery power, and how to access the battery to jump-start the vehicle. Check out our previous coverage for more information. Now, we’re taking a closer look at how to index (or “reinstate”) the automatic power windows, which is a step that’s required after power has been restored to help protect the windows.
Before we launch into this, it’s worth mentioning that if the 2020 Corvette C8 loses power and the windows are not indexed after power is restored, the windows could be damaged when opening or closing the doors. When properly indexed, the windows will automatically lower a small amount when the door is opened. When the door is closed, the window will raise to its previous position.
With that covered, here’s how to index the 2020 Corvette windows.
With power restored, first start the vehicle. Then partially open the windows.
Next, fully close the windows. Continue to hold the window switch briefly after the window has fully closed.
Next, fully open the window, and continue to hold the window switch briefly after the window has fully opened.
With those steps completed, the 2020 Corvette C8’s power windows should be properly indexed, operating as intended every time the doors are either opened or closed. These steps may need to be repeated any time the vehicle loses battery power.
As a reminder, the 2020 Corvette C8 is powered by the mid-mounted, naturally aspirated 6.2L V8 LT2 engine, which produces 495 horsepower and 470 pound-feet of torque when equipped with the optional Z51 Performance Package. The C8 is based on the all-new Y2 platform, with construction taking place at the GM Bowling Green assembly plant in Kentucky.
