Why does my front right side floor get wet when it rains or i wash it

Hi Deborah:
Time to trouble shoot..........
- Does the wet only happen when it is raining or when you wash the car? Possible windshield seal problem.
- Does the wet smell like anti-freeze or engine coolant (Heater core)
- Where does the dog lie after it has been swimming?

Get your heater core checked. May be leaking.

squirt it out with a hose or spray wand from a car wash place..

drains plugged up? flush with hose or pressure wand at car wash..

Question:Are you running your heater? If yes, your heater core is leaking. Its located behind the dash on the passenger side. Sorry to say, change it. You can do this yourself. Just a tight space to work, and hard on your patience.

If you have a wet seat then it is likely defective weather stripping around the window.

Try this. If the floor is dry, then it rains and the floor remains dry, only gets wet after a drive in the rain or on wet streets, you may have a hole somewhere.

Check for holes from missing rubber grommets or holes in the floorboard or firewall from rust. Check for any rust holes or missing rubber grommets under the car or on the firewall, anywhere water can splash up into the vehicle from driving in rain or running through puddles..

Check wet spots along the carpeting all the way up under the dash, if the wet spot is higher than the floor itself, you could be getting the water from splashing through puddles.

Any holes under the car or in the fenderwell even up on the firewall can cause this problem.

First check for any obvious signs of rust, if none are found then look for missing or defective rubber grommets.

most common problem is the a/c condensor tube is clogged and is under the car and needs to be cleared with compressed air. also the sunroof track has 4 drain tubes and the right front may be clogged or leaking. you can check that by pouring a cup of water down the right front drain tube in the sunroof track and see if water comes out by the right front wheel

You have a leaking windshield seal at the bottom of the windsheild rain gutter.

Go to a car wash with a good flashlight, and watch where the water comes from.
