Where is the sunroof drain outlet located on the Buick Envision?

[VanJulianna]

Buick Envision's sunroof drain holes are located near the sunroof sliding rails, which become visible when the sunroof is fully opened. All vehicles equipped with sunroofs have sunroof drain holes. Without these drain holes, the sunroof would leak during rainfall. Here are some additional details: 1. When the sunroof leaks: If the sunroof leaks, check whether the drain outlets are clogged with dust. Routine maintenance of the car sunroof doesn't require special procedures, just periodically inspect the surrounding sealing strips for damage and check the lubrication condition of the tracks. 2. Air conditioning drain hole: The air conditioning drain hole is designed to discharge water droplets formed by the condensation of surrounding air due to excessively low temperatures during air conditioning use. This drain hole is typically located at the bottom of the heater evaporator, above the front wall panel of the passenger compartment. Regular maintenance should also include checking these drain holes.
