What the Pros Prefer: 2014 Buick Lacrosse Cabin Air Filter Workflow
Glovebox damper protection, leaf debris clearance, and airflow arrow orientation.
Damper Cord Detachment
Shop Tip:Unhook the soft-drop damper cord on the right side of the glovebox first. Forcing the glovebox down without unhooking snaps the plastic damper arm.
Glovebox Stopper Tab Release
Shop Tip:Squeeze the left and right inner sidewalls of the glovebox firmly inward to clear the rubber stopping tabs, then let the glovebox swing downward freely.
Filter Access Door & Cavity Vacuuming
Shop Tip:Pine needles, dried leaves, and seeds sit on top of the old filter. Vacuum the shelf clean as you slide the old filter out so debris does not fall directly into the blower wheel.
Activated Carbon Filter Alignment
Shop Tip:Align the "AIR FLOW ↓" arrow to point toward the blower motor. Ensure filter pleats are not bunched or folded on the edges before snapping the access door shut.
