Where is the drain hole for the Buick Regal trunk?

[McAlejandro]

The trunk drain hole is located beneath the spare tire in the trunk, which is at the very bottom of the trunk compartment. 1. Drain holes are typically sealed with rubber plugs to prevent rainwater from flowing back into the vehicle. The trunk usually has one or two drain holes, and removing the rubber plug allows water to drain. If there is a water leak, the cause should be identified and resolved at the source. 2. Under normal circumstances, the trunk should not take in water, as any rainwater that seeps in is usually discharged through drainage channels near the taillights. 3. The purpose of drain holes is to channel rainwater out of the vehicle. Cars are equipped with many hidden drain holes, commonly found in the engine compartment, sunroof, fuel filler cap, and below the door panels. The functionality of these drain holes significantly impacts the vehicle's usability. 4. The sunroof and engine compartment drain holes are particularly prone to clogging. The engine compartment drain hole is situated near the air conditioning intake, making it susceptible to bacterial growth and potentially affecting the air quality from the AC. Sunroofs generally feature multiple drain holes, each connected to a drainage hose.
