The heater core would be the only cause of the souce of water drippng when you add to the cooling system. Check your heater core to heater hose connections first. Do the simple stuff before embarking on a "fantastic voyage". You may just have a slightly cracked hose as well.

I have a 2003 Chevy Tahoe, my problem is that the rear passenger side floor board is getting wet. Only spot in the whole vehicle that is wet. Im thinking that it is associated with the rear AC unit. I...


A clogged drip line would be my first suspicion.

Anytime warmer air passes over something cold, there will be condensation. It has to go somewhere, either under the vehicle, or onto the floor.

The fact that you are getting water there indicates that the evaporator is doing its job.

The passenger side floorboard gets wet =


is it only when the ac is on? there is a pan under the ac unit that has a hole in it to allow the condensation to empty. if that hole gets plugged it could cause the condensation to build up and back into the inside of that car. i unplugged mine and floor stayed dry

Very wet floor on pasenger side front and back after rain. Not from cooling system. Can't locate source even with hose.


Do you notice this after it rains>> This seems to be a common problem with Dodge Vehicles.

There is a seal on the passenger side Hood Hinge area. If this seal is cracked or broken or missing you will get water in the car every time it rains.
The water runs down the windshield in to the Hing area under the Hood.

You may need to take the hood off to get to the seal. First pour water over the area, if it comes in the car there is your problem.

You can seal it with any water proof silicone sealer .

Wet floor on passenger side in front and the extended part


The ac box is filling up with condensation.The drain ,is under the firewall,under the ac lines going inside the vehicle.Take a small diameter wire,and run it in the drain,back,and forth,until it clears,it will run out like a water fall,so look out.If this doesn`t work,then use compressed air to blow in the drain.

2005 chrysler sebring sedan water on inside of car


There is a rubber hose sticking out of the firewall on the lower passenger side, under the hood. With the A/C running you should see water dripping out of it, or if you let the car run for a few minutes notice a puddle on the ground. If you don't see water, the hose is probably plugged. Sometimes squeezing it a few times will work the crud inside it loose and water should start coming out. Same deal for the back. You'll have to crawl under the vehicle and look where the A/C lines go into the vehicle(it will be on the left or right side in the rear). There should be another rubber drain hose there. Hope this helps...

2004 Chevrolet Tahoe-front passenger side floor is wet


Check the heater core unit located underneath the dashboard on the passenger side of the vehicle. Even though your car's antifreeze is red, it may appear to be clear when there is only a small amount present. Was the liquid in the vehicle sticky and have any smell to it?

Water dripping onto the floor on passenger side below the dash broad


Under the passenger side of the vehicle, near where your feet are, should be a drain tube. This get clogged from time to time by road grime and usually insects, so carefully use a small screwdriver to clean it out. If this clogs, the A/C system cannot remove its own condensation and it backs up into the car.

Heater core?


ok most cars you wont see a physical drip because the box is sealed to the firewall it will run out the drain hole the same as the ac if bad enough they will leak down the insulation right to the floor board running pure water will cause rust but rarly causes the heater core to blow what you arre looking for is the problem that started it all why she was adding water to begin with you didnt mention the type of car and motor so i really cant get into diagnostic procedures you can bypass the heater core on most cars if it is using that much water you propably have a blown head gasket that will make the heater core blow let me know the type of car and I will help you diagnose it further
