Where Are the Drain Holes on the Buick Regal Doors?

[OCarmen]

Buick Regal's drain holes are generally located in areas such as the fuel tank cap, engine compartment, lower part of the door panels, and sunroof. The most prone areas to clogging are the sunroof and engine compartment. Below is relevant knowledge about the locations of the car's drain holes: 1. Air Conditioning Drain Hole: It discharges the condensate water generated during air conditioning use. The moisture outlet is usually located at the lower part of the evaporator box, connected to the chassis via a hose. You may notice a puddle of water under the car after the air conditioning has been running for a while. If the drain hole is blocked, water may enter the passenger side through the connection, soaking items like floor mats. 2. Engine Compartment Drain Hole: Located basically on both sides of the front windshield wipers, usually one on each side. The engine compartment is a relatively open environment, so wastewater and debris can flow into it along the windshield. Engineers have designed a water barrier at the rear of the engine compartment, along the lower edge of the windshield, and placed drain holes in the barrier's location.
