When the engine is cold, the shutter will be closed to keep the engine warm and reduce drag. As the engine warms up, the shutter will open to allow more air to flow through and cool the engine.

How to Fix an Active Grill Shutter

If you suspect that your active grill shutter is malfunctioning, there are a few things you can do to fix it:

1. Check the electrical connections. Make sure that the electrical connections to the grill shutter are tight and clean.
