* Sunroof Drain Tubes: Clogged sunroof drain tubes are a VERY common cause of water leaks. These tubes carry water away from the sunroof, and if they become blocked with debris, the water will back up and leak inside. Check the drain tubes (usually located near the front and rear corners of the sunroof opening) for blockages. You may need a small wire or compressed air to clear them.
* Windshield Seal: A leak around the windshield is another frequent problem. Over time, the sealant around the windshield can crack or deteriorate, allowing water to seep in. Inspect the seal carefully for any gaps or damage.
* A/C Drain Line: The air conditioning system has a drain line that removes condensation. If this line is clogged or disconnected, water can overflow and leak inside.
* Door Seals: Water can enter through poorly sealing doors, especially if the seals are worn or damaged. Inspect the door seals for cracks or deterioration.
* Weatherstripping: Similar to door seals, worn or damaged weatherstripping around windows and other openings can allow water to enter.
* Rear Hatch/Liftgate Seal: If the leak is noticeable towards the rear of the vehicle, the seal around the rear hatch or liftgate might be the culprit. Check for gaps or damage.
* Body Panel Gaps/Seals: Over time, body panels can shift slightly, creating gaps that allow water entry. This is less common but possible.
Troubleshooting Steps:
1. Identify the source: Try to pinpoint exactly where the water is entering the vehicle. This might involve carefully inspecting the vehicle during a rain shower or using a hose to simulate rainfall.
2. Check obvious areas first: Start with the sunroof drain tubes and windshield seal as these are the most frequent culprits.
3. Visual inspection: Thoroughly examine all seals, weatherstripping, and body panel gaps for any signs of damage or deterioration.
4. Interior inspection: Look for water stains or mold growth on the headliner, carpet, or other interior components. This can help narrow down the leak's location.
If you're not comfortable performing these checks yourself, it's best to take your Rendezvous to a mechanic or auto body shop. They have the experience and tools to diagnose and repair the leak effectively. Describing the location of the leak (e.g., "wet carpet under the passenger seat," "water dripping from the passenger side A-pillar") will help them pinpoint the problem.
