Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the vehicle battery to avoid electrical issues.

2. Inspect and Replace Weather Stripping

Tools Required: Flathead screwdriver, utility knife, adhesive cleaner, new weather stripping.
Remove the existing weather stripping by carefully prying it off with a flathead screwdriver.
Clean the surface where the weather stripping was attached using adhesive cleaner.
Cut the new weather stripping to the appropriate length and press it firmly into place, ensuring a snug fit.

3. Clear Drainage Channels

Tools Required: Compressed air or a soft brush.
Locate the drainage channels at the bottom of the rear hatch.
Use compressed air or a soft brush to clear any debris or blockages from the channels.
Ensure that water can flow freely through the channels during a water test.

4. Realign the Rear Hatch

Tools Required: Socket set.
Inspect the hinge bolts for tightness; if loose, tighten them with a socket set.
Adjust the alignment of the rear hatch by loosening the hinge bolts slightly, repositioning the hatch, and retightening the bolts to secure the hatch in the correct position.

5. Verify Rear Window Sealing

Tools Required: None.
Inspect the seal around the rear window for any gaps or deterioration.
If necessary, remove the rear window trim and apply a bead of high-quality automotive sealant around the edge of the window; allow it to cure as per the manufacturer’s instructions.
