Water on floor under carpet, after moderate rain ! 1973 T

[993anorak]

Dear all;
Got a real surprise !
After having driven under moderate rain for less than 15mn, I noticed lots of water at the passager side, front and back, under the carpet...
Any idea how it came there ?
I drive a 911 T 1973
Many thanks for your advices.

I would say front or rear screen seals, or both…….but then I always do!

Yes, thanks but I then should get water on the driver side also...

Depends where the leak is.......we've dealt with dozens of water leaks and 99% of the time its coming through the screen.

Please I need confirmation : 'screen' is 'windshield' ?

It could be front or rear screen. It could leak on some days and not others and also be dependant on the angle of how you're been parked. Sometimes these leaks are hard to trace and you need to water test specific areas to try and track where/how the water is getting in but it will nearly always be through the front or rear screen seals.

We helped with an 911 recently where it was impossible to tell how water was getting in, in the end the front screen was taken out to fit a new seal as a last resort and only at that point could you see evidence that it was indeed the screen seal

HTH. Good luck.

Many thanks indeed for your good advice.
My screen needs to be changed anyway because of stone impacts
I'll keep posting to update

Check below the rear seat bases and parcel shelf too, mine had rust - all down to a leaky rear screen seal.

Or drill holes and let the water through !

Hole in the floor - look inside the front wing towards the passenger footwell or under the car near the sill.

Just welded one up for a friend.

Also check the drain tube that runs from the heater blower down through the car bulkhead and out the floor at the bottom, it drains the water from the air vent near the screen down the plastic blower box and into the tube near the smugglers box.

Many thanks, the car is between hands of a mechanic with ALL your advices.

I have been following your advices and had the joint changed... but my mechanic found the same hole as here....
I actually think that the water came via this LARGE hole... :

OUI, the COA did not mention A/C, and was fitted by Porsche Dealer in the US...

Air con was more often fitted by the supplying dealer rather than being Factory-installed.
