Where are the drain holes located on a Honda Civic?

[VanGraham]

Honda Civic door drain holes are typically located at the bottom of the door panels. Each door has at least two drainage outlets. Most vehicle models don't have separate drainage pipes inside doors - rainwater entering the door will flow downward and exit through these drain holes. Since the drain holes are positioned low, they can easily get clogged with mud when driving frequently on muddy roads, so owners should regularly check for blockages. If water accumulates inside the door, the thin waterproof membrane on the inner door panel cannot withstand heavy rainwater intrusion, which may damage components like window regulators and audio systems. Door drain holes can be cleared using stiff objects like wire, but take special care when cleaning those hidden beneath rubber seals to avoid damaging the seals. Besides door drain holes, vehicles have other drainage points including sunroof, engine compartment, under spare tire in trunk, fuel filler flap, and rocker panels. The most prone-to-clog locations are the sunroof and engine compartment since these areas are often overlooked - owners should perform routine inspections.
