Why does the sunroof drain pipe joint come off?

[RoseAnn]

The sunroof drain pipe joint comes off because the adhesive was not applied properly. Below is relevant information about drain pipes: 1. Air conditioning drain hole: It discharges the condensate water generated during air conditioning operation outside the vehicle. The moisture outlet is generally located at the lower part of the evaporator box and connected to the chassis via a hose. Therefore, you may notice a puddle of water under the car after the air conditioning has been running for a while. 2. Engine compartment drain hole: It is usually located on both sides of the front windshield wipers, with one on each side. The engine compartment is a relatively open environment, so sewage 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 incorporated drain holes in the barrier. 3. Sunroof drain hole: A sunroof is a must-have feature for most car buyers. However, installing a sunroof involves creating an opening in an area that requires excellent waterproofing, making proper drainage measures even more essential.
