Where are the drainage holes of the Buick Regal located?

[EmilioFitz]

Buick Regal has a total of 4 drainage holes, located at the fuel tank cap, the four corners of the sunroof, the lower part of the front and rear doors, and both sides of the front windshield wipers. Among them, the most prone to clogging are the drainage holes in the engine compartment and the sunroof. Below is the relevant introduction: Function: The purpose of the vehicle's drainage holes is to drain accumulated water from the vehicle to the outside during rainy days. During normal driving, if not cleaned in time, it can eventually lead to water ingress inside the vehicle, and in severe cases, may cause irreversible damage to the vehicle's mechanical parts and electronic devices. Precautions: After purchasing a new car, it is essential to promptly check the drainage holes on the doors to ensure they are open. If the drainage hole plugs are not opened, water may accumulate in the trunk during rain or car washing, leading to rust over time and affecting the car's lifespan.
