Why would your car floor keep getting wet even though there aren't any visible holes?

Answer 1

Your coffee holder isn't holding your coffee? :-) If it doesn't smell like antifreeze (heatercore leak) then I would be suspect of a plugged drainhole in the wiper transmission cowl area. This time of year leaves will plug it up and water flows in through the firewall area. It would also be good to look behind the glovebox area to see if a harness or hose that may pass through the firewall isn't caulked well enough. Some other suggestions: * I had a car that had a deer run into the driver's door while we were going down the highway. The body shop fixed the door where by looking you couldn't tell it had been hit. But every time it rained the car would get wet inside. They did a bad job aligning the door and it didn't press the door seal tight enough to keep it from leaking. So if the car has been wrecked before you bought it or since you had it your door may not be aligned right or possibly an old door seal. * Could be a leak from a bad windshield seal. Wonder if it could even be condensation leakage from your air conditioner too. * I would say the drain tube on the air conditioner condenser is plugged.in my 2000 grand prix it has plugged with grime several times, causing it to flow into the passenger side floor right under the blower motor. find the tube under the car and blow into it with an air compressor. this will unplugg it.the tube should be right under the condenser in your engine bay. * Check the heater core, and pray that isn't the problem. * When asked to repair a waterleak I like some history on the car. Most waterleaks on used cars are the result of some sort of repair. What has been fixed on your car? If you have a sunroof/moonroof, the drain holes can be clogged. If you have trees or other debris that falls on the car, this is a big problem. The drains should be cleaned a couple times a year. This debris also clogs the drains in the cowl in front of the windshield, causing water to come in the fresh air vent in the heating-air system. This usually causes a leak on just the passenger side.

It is possible that your car AC drain hose is plugged with dirt and the condensate is instead collecting and dripping into the vehicle. I tried not using the AC for a day but when I got into my car the next morning the ground was still soaked. Could there be problems with the drainage from my sun roof?
