Ensure the vehicle is parked on a level surface and the engine is off.
Safety warning: Disconnect the battery if working with electrical components.

2. Clear Sunroof Drains

Tools Required: Flexible wire or compressed air

- Inspect the windshield seal for gaps or deterioration.
- Carefully cut away the old sealant with a utility knife and apply new urethane sealant around the edges of the windshield.

5. Check Heater Core

Tools Required: Coolant, hose clamps
- Inspect the heater core for leaks by checking for coolant pooling in the footwells.
- If leaking, remove the hoses connected to the heater core, replace it if necessary, and refill the coolant.
