The past few times it has rained, the passg side front floor board area fills with water. I can't find a leak around the door seal. Any other areas that water could leak into?

Based on our research the RAV4s with wet floors are usually, but not always, clogged sunroof drains or drain outlets. Other RAV4 owners found that the body trim surrounding their windshield or even the fender panel had degraded and failed, allowing water to seep in during heavy rain.

Most water leaks come from around the windshield area. Has the windshield been replaces recently? If so it may not be sealed properly. Another area where water may penetrate is through the cowling area under the wiper blades/arm where fresh air enters the car. There are water drains under this cowling allowing water to drain and if they are plugged with leaves/debris, water will enter the vehicle. Is the vehicle rusted around the windshield area? If so, suspect this to be the source of water intrusion. Most glass/windshield repair companies will diagnose water intrusion problems
Someone in the car watching for leak, someone outside the car with a hose.. Gently apply water to the door area and person inside looks for the leak... Another possibilty. If the water is comning from under the car it can be a rusted place or a body separaion.. harder to find. It can be comning in from around the windheild seal and running down the interior firewall. This is how a shop would find the leak.. but they would charge you for it..
At the base of the windscreen there is a gutter (Phelumn chamber)that drains the water out and down past the front wheels in side the mudguards. This gutter blocks up with dirt/ leaves /insects and will rust out and allow water into the cabin area especially if you are in an area that used salt in winter on the roads
several qs. What year make and model is the car? Is car level when water fills floor? Does it always happen every time it rains fairly heavily? Is the trunk always dry? Talk to other owners for their experience.
A water leak under the dash could be the heater leaking near the glove box, or a windshield leak, or sometimes the drain tube for that area has gotten plugged up and needs to be cleared out. Most times a little blast of air pressure will do it.
Hope this helps.
you will find under driver and passenger seatsunderneath the car there are plugs to let water out when it gets in maybe , maybe the plug is missing and water is getting in when raining road surface water hope this helps
pull your carpet up near the leak area and look for muddy body seams. it is possible one of the factory body seams are leaking- possibly in the cowl(under wipers) area, especially if it leaks when the car is sitting. there will be dirt/mud around the seams that are leaking. also you can check door seals by running the car on HIGH DEFROST with all doors and windows closed. spray around with a 50/50 soapy water solution. obviously bubbles will form around your leak.
