Where is the drainage hole in the trunk of a Jetta?

[McMichael]

Jetta's trunk drainage hole is located beneath the spare tire in the trunk, which is the lowest part of the trunk compartment. Below are specific details about other drainage holes in a sedan: 1. Air Conditioning Drainage Hole: Condensation water generated during air conditioning use is expelled outside the vehicle. The drainage outlet is typically situated at the bottom 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 drainage hole is clogged, water may enter the passenger compartment through the connection, soaking items like floor mats. 2. Engine Compartment Drainage Hole: This is generally located on both sides of the front windshield wipers. The engine compartment is a relatively open environment, so wastewater and debris can flow down the windshield into it. To address this, a water deflector is designed at the rear of the engine compartment, along the lower edge of the windshield, with drainage holes positioned in the deflector.
