I always get a puddle if water on my floor after the rain and can't figure out why. I've sat in the car while it's being sprayed and can't see any water seeping the the door any advice on where to look next? I've already verified the drains in the front aren't clogged.

When you say the drains in the front are not clogged, I assume this has a sunroof?

If that is the case, then the best thing to do is remove all the trim from the area where you are finding the water and then we have to run a hose in a specific manner.

You want to remove any nozzle from the hose so that the water cascades over the roof and windshield. This will simulate a monster ran storm.

Then with the trim panels removed, you will be able to see the path of any water coming in.

Once you locate the general area where the water is coming in you will want to pick up some water tracing powder from a local parts store. This is kind of like baby powder, but the point is that you will put it in the area where the water is coming in and then water test the vehicle again. The water will leave a track of where it is entering the vehicle telling us exactly where to repair.

Let me know if you have done this and then we can take the next steps.

Thanks

Okay. That makes sense. I didn't think this had a sunroof.

These can be frustrating, which is why there are people that have companies specifically for water leaks in cars. However, if you take your time, you will find it and can fix it by sealing that area.

If you get to the point where you know the area but can't get to it, you can use a product called flowable sealer. It is made by many people, but I would use the 3M product. Basically, this will remain liquid until it reaches the crack, fill it and then harden.

Thanks for the update. Let us know what questions you have.
