Just had my mother arrive,58 Fiesta zetec. Water is coming

This answer was rated:

Just had my mother arrive,58 Fiesta zetec. Water is coming into driver side front and back footwell. Carpet dry on top but sound proofing underneath is saturated and water on the chassis floor.
Cannot see any holes underneath(only done 40k miles).
Any suggestions?

Hello, I hope the following assists you.

Although the carpet appears dry this is due to the fact the sound deadening absorbs all the water that comes into the car.

The first thing to check is the door(s) on the driver's side. The doors are designed for water to run inside it and out of the drain holes at the bottom. Make sure the drain holes are clear. With the aid of an assistant stay in the car while water is poured on the door, look for any signs of water coming from the bottom of the interior door trim, if the weather shielding behind the trim fails or has a hole in it water can come through and run behind the trim then drop from the door into the car.

Another point is if the car has air conditioning when this is turned on make sure condensation from the heater assembly is draining underneath the car, if the drain tube is blocked condensation comes from the heater assembly through it's joints into the car.

The only way to thoroughly dry the carpet and sound deadening is to remove the seats then the carpet. If there isn't a leak from the doors or heater then having the carpet removed will assist finding the water ingress, the big problem is water travels through the sound deadening so the water can drop in the front but as the deadening becomes saturated it will be soaked all the way to the rear.

I hope this helps, let me know if I can assist further and I'll reply as soon as I'm able to.

Best wishes,

Thanks Sean

I'll pop the rating through as good but can you assist with just one more on this?


I'm not the best on cars, but the doors seem okay, it's raining so cannot see water coming in under the trim anywhere. Run the air con for 20 mins and there doesn't seem to be any water dripping out which would indicate the pipe may be fouled, where would the air con drain tube be on the that I can jack up and take a closer look?


Car is out of warranty but would you expect a Ford dealer who regularly services the car to be helpful and FOC or is my mother looking at hefty bills in your personal opinion?



Thanks again

Hello again,
You should be able to access the air con drain in the car, it comes off the bottom of the heater box on the drivers side, you may need to pull the carpet back to see it.
I would be surprised if the dealer did this for free, finding water leaks into a car is quite time consuming.
Let me know if I can help any more.
