WARNING: This page is about a different car, the 2021 Chevrolet Tahoe and 2021 Chevrolet Suburban. However, it is still accessible from the selected car via links, so may be relevant.
The compressor is a dual stage positive displacement piston air pump with boost mode driven by a 12-volt DC permanent magnet motor. The compressor draws air from the atmosphere or reservoir, compresses and dries and supplies it to the Air Suspension Controller. The compressor exhausts air to the atmosphere from the Air Suspension Controller.
