Wet Driver floorboard 2011 LR4

Jermgallo said:

Last night we had a massive rain storm and this morning I had water standing in the floorboard on the driver side. Any ideas or suggestions on this issue would be helpful. This is the first time this has happened and it has been out in other rain storms before with no issue.

pop sunroof, remove interior A-column trim.

You will see some drain holes towards the outside forward edges of the sunroof. From the inside, you will see some plastic tubing and connectors that connect to these holes.

You need to get those unclogged. LOW pressure compressed air works fairly well. When you get them clear, you should be able to apply water to the drain opening in the sunroof and watch the water hit the ground roughly from behind the front fender air intakes on both sides.

To add to what has been suggested, which is good . . .
- The plastic drain tubes can clog with pollen and if you try and blow them out with compressed air you can blow the tubes loose in the pillar. That is why the suggestion for low air pressure. You can also use a 5-foot length of mechanics wire with a loop on the end
- In salty climates I have seen the metal parts of the drain tubes rot out, necessitating more extensive repair
- Rain water runs down the windshield and into trays on the firewall. The trays have drains called cowl drains, to drop the water on the ground. Those can clog with leaf debris and cause water to back up into the car. Clogged cowl drains are a major source of interior electrical damage in the northeast US
