    Thanks guys but there is no sunroof and I have not used the AC in a couple years. It leaks when water runs over the windshield so only if it's raining or I wash it. I had the windshield replaced in April, but it did not rain here all summer, so only recently noticed a puddle under the floor matt. Could there be a bad gasket or seal under the dash where the air intake attaches or is there even a seam located in that area?

    ps I'm sure it's not coolant so the heating coil is ok, it's definitely outside water finding its way in.

    Problem solved.... after removing the metal trim around the newly replaced windshield I found a very small screw hole at the lower edge of the windshield sealant. I'm told, by the company who replaced the windshield, that years ago metal clips to secure the glass used to be screwed to the metal and this was most likely an old hole. Bottom line is this was a hole they should have seen and sealed when the glass was replaced!

SOURCE: water leak on fwd passenger side after every rain storm

If your car has a sunroof, there are drains from the front corners of the sunroof, and they drain down the sides of the windshield pillars, and then empty out on the ground.

What I would do is open the surnroof, and pour water into the front corners, and then oobserve where the water drains out. If you have a difference in water drainage between the left and the right sides, I would think that you may have loose sunroof drain. They commonly come loose at the sunroof corners. This will allow the water to pass down the windshield pillar, and onto the floor.

Also, I would check the condensate drain tube for blockage. Pull back the carpet, under the glove box, and fins a black hose that pokes thru the firewall. Pull it out, and see if it is blocked internally. If this tube is clogged, water will build up in the heater box, as the black tube is the drain for the heater box.

One of the two above solutions will cure your problem. I see both quite often.

Thanks for choosing FixYa for assistance.

SOURCE: 2002 Toyota RAV4 passenger side floor Water

Hi, we also have a 2002 Toyota Rav4 and developed a leak in the front driver's side of the car. After much research, we discovered that the drain wells from our sun/moon roof were clogged. If you have one of these, I suggest that you open the sun roof and look carefully. You will notice some tiny little holes in front and in the rear of the sun/moon roof tracks. Over time, these become clogged with dust and debris. You need to find a long, sturdy piece of thin wire and run it down the holes. To test if you have properly unclogged these, take a small amount of water and pour it down the holes. You should see water coming out of the drain wells under the car around the rear of the front tires. Hope this helps.

Is there a condensate drain for blower motor compartment under the dash of a 2004 Chevy Silverado 2500HD?

Look for cracked sealant between the firewall and the body near the A post. Look under the bug screen by the wiper arms.I had 18 new Buicks that all leaked water with missing sealant in the seams where the firewall joined the A post. The case that hold the heater core and the AC evaporator has a gasket on both sides of the firewall. The gasket will allow water into the cab if some of the mounting bolts shake loose ot the gasket dries out. It's only paper.

I have a 1992 VW Cabriolet which leaks badly during heavy rain. Some small seepage comes in around the clamps at the top of the windshield, but the major leak occurs on the passenger side floor under the...

windshield seals are usually not the problem: Here's the secret: There are 2 round rubber drains that are meant to get water away from that firewall: Yours are clogged!
The solution is simple: Open the hood, look to both the left and right of your blower fan (that's where your water was coming from, by the way), check both and I promise you, they are both blocked. Now take a long screw driver and push trough any leaves or gunk in there and then take a garden hose and spray it into both holes and voila! No more water inside Cabby!
Enjoy your dry Cabrio! Cheers!

Water was leaking inside on passengers side, now

HVAC drain tube was blocked and condensation could not drain to the outside of the vehicle

as a result the water pooled inside the HVAC case leaking on the inside and killing your blower motor and probably blower motor resistor

clear the drain, replace the blower and resistor and you'll be back in business

Rain water leaking from under glove box, heater area, is not antifreeqe, iam sure it is rain water

The evaporator drain might be clogged. Get under the truck or open the hood and look for a rubber nipple coming out of the firewall on the passengers side. Try sticking something in this hole to release whatever might be stuck in there, usually leaves or sediment. Be careful, don't go crazy pocking something in there. The evaporator core might be near the drain hole, you don't want to poke a hole in it.

Sounds like your drain is pluged. The drain is on pass. Side on fire wall. More than likely will have to get under car to find it. Try shooting some compressed air into drain port

Rain water leak

Did you have the windshield replaced recently? This is typically caused by faulty installation of a windshield. Sometimes it can be fixed by adding windshield sealant (polyurethene, not silicone) where the windshield is adhered to the subframe - most likely along the bottom edge.
