Where is the sunroof drain outlet of the Mercedes-Benz GLK350?

[SanLaura]

The sunroof drain outlet of the Mercedes-Benz GLK350 is located near the A-pillar at the front of the sunroof. Drain hole location: To locate the drain hole, you need to open the sunroof. There is a tube inside the drain hole, which runs through the A-pillar, allowing water from the sunroof to flow to the bottom of the car. If the sunroof drain hole is clogged, it can cause water leakage from the sunroof. You can find drainage outlets on both sides of the sunroof track. Pour water into these outlets and observe whether the drainage pipes are clear. Check if water flows out from the front fender liner. If it is blocked, inspect the cause and clean any debris from the sunroof track. Use an air hose to blow out dust from the sunroof opening. Maintenance methods for the sunroof include: Avoid opening the sunroof on bumpy roads to prevent excessive vibration that may deform the track. When washing the car, avoid directing high-pressure water jets at the sealing ring, as this can deform it. Regularly clean dust and leaves from the drain holes and grooves to prevent clogging or reduced performance of the sealing ring. Apply lubricant periodically to reduce track wear and extend the sunroof's lifespan.
