1. Open the sunroof fully.
2. Locate the drain holes at each corner of the sunroof frame.
3. Use a flexible wire to gently clear any obstructions from the drain tubes.
4. Test the drains by pouring water into the sunroof channels to ensure proper drainage.

3. Inspect Seals

Tools Required: Soft cloth, silicone sealant (if needed)
Instructions:
1. Visually inspect the windshield, door, and rear hatch seals for any signs of damage or gaps.
2. Clean surfaces with a soft cloth to improve adhesion if sealant is needed.
3. Apply silicone sealant to any compromised areas, ensuring a tight seal.

4. Check and Repair Cooling System Leaks

Tools Required: Coolant, pressure tester (optional), socket set
Instructions:
1. Visually inspect all hoses, clamps, and the radiator for signs of coolant leakage.
2. If leaks are found, replace damaged hoses or tighten clamps as necessary.
3. Refill the cooling system with the appropriate coolant if levels are low.

5. Address HVAC Drainage Issues

Tools Required: Compressed air (optional)
Instructions:
1. Locate the A/C drain hose (usually located under the vehicle).
