Where is the sunroof drain hole of the Buick Regal?
1 Answers
The sunroof drain holes are located in the two corners on the left and right sides of the sunroof. If you can't find them, you can pour some mineral water and observe the direction of the water flow to locate them. Here are some relevant details: 1. Function: The sunroof drain hole is designed to prevent rainwater from entering the cabin. All models with a sunroof have this structure, but it requires regular maintenance. The sealing strips near the drain holes should be replaced once a year. 2. Maintenance: Check the sunroof tracks at least once a year. Fully open the sunroof and check for any dirt or debris in or around the tracks. After cleaning, lubricate the sunroof tracks with grease to prevent rust and ensure smooth operation.
