problem details
2002 Honda Accord 186,000 mi,
Wet in driver's side floorboard ... no windshield leak. Continues to have a small puddle on drivers side after every rain.
2002 Honda Accord 99,000 mi,
Water in passenger back set when rainfall
When it rains the drivers side carpets front and back get soaking wet? Sealing the windshield did not help?
2002 Honda Accord 110,000 mi,
The problem was: very wet floorboards in front (and possibly also rear) of the car. This produced a very bad odor that persisted for a long time. At first I thought it was a windshield problem. Rather, there was an issue with the sunroof (moonroof?) hose. Either it was disconnected or clogged. A local Honda dealership repaired it; took two visits, the first visit didn't quite "take."
After a long day of rain, the inside passenger side of my 2001 Accord LX was soaking wet. The water splashed into the console and the seat and door and floor on the front passenger side was soaking wet. First time this happened. Assuming I closed the sunroof all the way, which I believe I did. hmmmm. Now the car smells funny. Please help. Addition: The inside ceiling between the sunroof and the door was all wet. above the door.

Use a long nylon extension attached to a compressed air gun. There are 4 drain holes in the sun roof drip pan; 1 in easch position: The right & left front and the right & left rear. Open the sun roof. The fronts are easy to locate and blow clean. The rear drain ports you will need to "fish for" but are easy to locate & you will feel then the tip finds the openiing. Simply insert the blow gun nozel into the drain hole & blow for 5 seconds to remove debris covering the drain exits in the wheel wells.
2002 Honda Accord 48,000 mi,
water in trunk under spare tire. source of leak found to be left and right trunk to quarter panel body seams. Resealed over factory seal with RTV type caulking. Also, checked and cleared moonroof drain connections to the wheel wells. A year later found water in right rear passanger foot well. No clue yet where this is coming from.
Water in rear passenger seat. Think sunroof is leaking. Could drain holes be plugged. How do you unplug them. Where are they located?

Water leaking on driver side, resulting in soaked floor mats. I blew out the drains on the moonroof and leaking stopped, but it has started again. I think I I'll use a compressed air nozzle this time. Not totally sure this is the final solution to the problem.
