Question about 2004 Lexus RX 330

Cabin fills with water when it rains

I have experienced the same problem of the cabin floor filling with water during rain. At first we thought it was the sunroof. Not the problem. Then the fault was placed on the installation of sat radio antena. Wire was routed under the seal at the top of the tailgate. That was quickly disproved.
Finnally found that the weld just above where the struts that hold the tailgate open have failed. Apparently the repeated opening and closing of the tailgate causes too much stress.
a quick solution was to use bathroom or silcone caulk across the top of the joint.

If you have a moon roof and you have changed, disconnected, or ran down the battery recently. You need to normalize the moon roof for it to close properly. See your owners Manuel

SOURCE: Lexus ES300 trunk leaks when it rains

This may sound odd but if you can put a small person in the trunk with a flashlight while you pour water in the areas suspected, they can trace the leaking area, believe it or not I used to use this method while I was a Ford mechanic. Otherwise, maybe you can apply clear or black silicone to the area or remove the screw or bolt and coat it with silicone and replace it.

SOURCE: Water in Floorboard tailgate area

Gasket on the door has gone bad and needs to be replaced. It seems like the door gasket is not sealing properly and allowing water into your vehicle or you have a leak in the bottom of the vehicle that needs repairing. But that is more then likely not the problem

SOURCE: water leaks onto the front

most likely when some one replaced the windshield they did not put the self sealing riviets in that hold the trim on. remove the cover on the side of the windshield and look. if that is not it check the moon roof drain tube runs in the a pillar

SOURCE: Extreme rain for several days, has caused Water

one other thing that could be happening is the sunroof drain tubes could be disconnected. Ive seen that happen when the windsheild is replaced.

Most newer cars don't have drain plugs in the floor. So it must either be your window does not close tightly or the rubber seal is completely gone around the lower door.

Water leaks can be really evasive, It could be coming from the rear glass where it seals against the body or it could be coming from the seams where the quarter panels and roof panels meet. (at the lower corners of the back glass/trunk lid area.) The best way to find these things are to water-test the vehicle. You can look for water entering the trunk area if you can find someone you trust to run water over the trunk and back glass area while you are inside the trunk with a flashlight. If this does not yield any answers, it may be necessary to remove the rear seat and interrior panels and headliner to look for water running into the cabin area. If you see any water, follow it uphill to locate the point of entry. I have even seen windshield area roof leaks fill the rear floor pans of a car that was parked nose-up on a hill.

Saab 93 convertable, Rain water fills the drivers footwell when the car is parked downhill.


I am not sure if it is the same problem I had with my '04 93 SS, but there is a cabin air filter that has a drain next to it that allows the rain water to run down to the ground. Mine was clogged up with leaves and other junk which caused the rain water to leak through the filter into the cabin. Being that yours is a different body style, your filter may be on the drivers side which would cause this. I would try to look up where your Cabin Air Filter is and try to clean the drain.

most likely cause is water intrusion through the cabin filter

pull the filter
if wet then you need to find something that diverts water away

Everytime it rains really hard rain gets in the car. There is a 2 or 3 inches in the passenger side floor board.


I have the same problem with my 91' 318. Water is coming in from the outside air intake at the base of the front windshield, under the black vent covers. If the basin fills up, water enters the vent system throught the outside air intake. Solution: there is a drain line at the fire wall, easily accessible between the firewall and engine block. It drains water from the basin. It becomes clogged with dirt, and prevents water from draining. However, after further inspection of mine I noticed that during periods of HEAVY rain, even a clean drain line is inadequate to drain that volume of water and the same happens. See attached link. Good Luck
