Symptoms
Water sloshing inside the liftgate or dripping from the inner panel with the gate open, after rain or a wash.
The fix, step by step
- Under the liftgate, find the small rubber plugs in the drain holes and pull them so water can escape — a 4Runner6G.com owner had water gush out.
- Leave the large centre plug in place; another owner points out it's an access hole, not a drain.
Tools & part numbers
- Trim tool or small screwdriver
