GM Parts Club
By the end of October you are driving in the dark on both ends of the commute. Here is what to actually look at, using a 2017-2019 Buick LaCrosse as the example.
Body and Exterior
Watch for a door handle that pulls with no resistance. Not a scheduled item. These are damage and failure replacements.
Factory paint codes only work if the substrate and primer are the same.
Sensors, Cameras and Driver Assistance
Watch for a backup camera image that flickers, goes blue, or shows lines. TPMS sensor batteries typically last seven to ten years and are commonly replaced as a set during a tire change.
Camera and radar aim is a service procedure, not a bolt-on.
Glass and Wipers
Watch for wipers that park in the wrong position. Blades every six to twelve months. In North Texas, summer heat kills blades faster than winter does.
Windshields with acoustic interlayer, HUD or camera brackets are not interchangeable with base glass.
The Short Checklist
- Mirrors: Trim level changes almost every exterior part. Take a photo of the connector on the part you are replacing before you order.
- Park assist sensors: Painted park assist sensors are ordered in primer and painted to your code. Confirm your paint code before ordering.
- Wiper blades: Driver and passenger blades are frequently different lengths on the same vehicle.
