I'm sure it's from the heater core. The water still go through it, You might get a wire hanger and stick up the drain hose on passengerside firewall,This get's stoped up sometimes and back's up to your floorboard. If this don't work your going to have to replace your hearer core, This cost around $25 but have to take the bottom dash out to replace. Best of luck to you. l

Water leak driver floor board


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.

We have water leaking into the interior of the car with the air conditioner on. Seems like the condensation drain is plugged. where is this located on this car?


There is a drain from the condensation from the cooling coils and so this could be blocked or the hose had come off in postion when the mat or the floor was cleaned.
please check this out , clean the hose or connect the hose back to the outlet point under the dash board collection tray.

My 1999 Toyota Avalon has a leak that I can't find. When it rains the floor boards on the passenger side are both wet. I have a sun roof so how are the floor boards getting wet and how do I fix it?


There are 2 'weep' holes where tubes come out of the firewall and sometimes they get plugged. Get some compressed air and blow them out.

Also, inside the vehicle, there is a plastic pan that catches all water that might come down from the evaporator or leak from the outside into the interior of the car when the seal is not good between the firewall and the plastic pan that spans from the left to the right of the car under the dash board.

Get some expanding foam in a can and spray it up against the juncture between the firewall and the plastic water pan. This should seal out the problem if done properly.

Over time, the original foam seal goes bad and can actually flake away.

You mentioned the sunroof. Make sure that all the gaskets and that the sunroof does not leak onto the floor. This can be another source of wetness for your vehicle.

Try testing it by spraying water down from a hose to the top of the vehicle, or dumping a bucket of water all at once on the top of the roof. If it leaks, try using silicon sealant to seal any gaps that may exist in the sunroof.

Hope this helps.

1999 Pontiac Sunfire Leaking water in Passenger Interior


The evaporator drain is plugged with debris and filling up the heater case. Remove the 90 degree elbow and clear the drain hole at the case.(pencil or piece of wire) You will know that's it when it dumps out a half gallon on the floor. Be sure to reinstall the elbow to keep out rain/ road spray.
