Passenger footwell leak - Mazda 3 Tamura 2012
« on: March 23, 2021, 09:04:07 AM »
Hi everyone,

I've had a leak, with puddles of water from front to back, but just on the passenger side, for around a year. I've taken it to several garages who have not been able to locate the source of the leak (and some won't even touch it).

I've removed the passenger seat and got the carpet up, and dried everything out but it continues to get wet (even when it hasn't rained), and I have a problem with condensation, and now mould, inside the car.

I believe I've roughly narrowed down the site of the leak to the passenger footwell/wheel arch but now I'm stuck.

The last garage I took it to checked that the drainage wasn't blocked by pouring water down both sides under the hood and the water drained underneath as expected.

He suggested that it may be a common issue with Mazdas and that I might find some answers on a Mazda forum.

Has anyone else had this problem and managed to resolve it?

Thanks in advance for any help!

There are several reports on this forum about water ingress to both passenger and drivers footwell area.

Regrettably although there were many suggestions as to the cause, no members ever reported a solution.  The thing being maybe something suggested might have helped, but nobody came back and said that.
This is a problem with any forum.

I would suggest that you investigate whether you are losing water from the cooling system. It might be that a heater hose is loose behind the dashboard.

I suggest you go back to the HOME page and use the search field from there. That searches the whole of the forum.  Try using different search words.   Good luck.
And check out those hoses.  :)

Ok thanks Willpower. I did search for 'leaks' from there before posting but couldn't find what I was looking for.

Could possibly be a leaky heater matrix - I had a similar problem a few years ago on a different vehicle. Solution was a replacement heater matrix.

To stop it leaking I was told to put the temperature selector on cold until it was replaced. That temporarily stopped it leaking into the passenger footwell.

Do you find yourself topping the coolant up fairly regularly?

If it was as long term as it sounds and it's the heater matrix I'd expect to have noticed it going somewhere.

Has the car had a replacement windscreen at some point in it's life?

Thanks djkj and StevenRB45

The coolant level is stable and I haven't topped it up for a long time.

I'm not sure about the windscreen but now you mention it I remember someone saying it's not a genuine mazada windscreen so I'll dig out the paperwork and have a look. If so, could that be the culprit?

Bonded windscreens can be a mare to get right when replacing.

If you get them wrong they can and do leak.
