What are the reasons for water leakage in the car A-pillar?
1 Answers
Water leakage in the car A-pillar can be caused by: 1. Blockage of the sunroof drainage holes, preventing rainwater from draining in time and causing it to flow along the duct interface into the interior of the A-pillar; 2. Aging of the windshield sealing strip leading to leakage; 3. Aging of the window sealing strip or poor sealing of the roof rack mounting holes. The A-pillar is the connecting pillar between the left/right front and the roof and front compartment. The body pillars from front to back are the front pillar (A-pillar), middle pillar (B-pillar), and rear pillar (C-pillar). For sedans, these pillars provide structural support and serve as door frames. The A-pillar is a key component supporting the vehicle's structural strength—the higher its strength, the better the car's impact resistance.
