Water leaks into the drivers side floor pan

Guest

New member
I have a 2000 2.7. I noticed recently that when the car is parked and the temperature drops at night the inside of the windows mist up. Thinking that it was probably water from my shoes dripping on to the carpet as I got in I thoroughly dried the car out. Strangely during the recent dry spell the carpet behind the drivers heel mat always felt slightly damp, so I dried it again using a fan heater.

There were no hood leaks, and no sign of drips from the roof seal or around the panel. After the very heavy rain we had on the 19th Dec, I immediately checked for leaks and a damp carpet, and found just a damp carpet. When I checked today some 12 hours after the rain the carpet on the drivers side was soaked, very worrying.

Has anyone had a similar experience and found a possible answer.

Any advice would be appreciated before I have to take the car in for an expensive strip out?
 
Check the botton of the door. If the carpet trim is wet you could have a defective door membrane. These are a very common Boxster problem. So simple to fix it only took Porsche Centre Guildford 3 visits to cure mine in my S.
 
Thanks for the quick reply Andy. If it took AFN three visits, then perhaps they can do mine in one.
I'll keep you posted on the results.
 
You also need to check that the front drain channels are not blocked with leaves (under the battery cover area)
 
Thanks for that Black8OXSA, I have just done that and there were quite a few leaves etc in the drain channels. In the nearside channel I found a loose yellow rubber plug shaped like the end of a condom, can't imagine what that was for!!!!
Also checked for leaks through the door membrane as Andy suggested, but that was all clear. Keeping my fingers crossed.
Thanks again for the advice.
 
I haven't solved the problem by clearing the leaves from around the drain holes either side of the battery.

After the last heavy overnight rain the carpet was soaked again, but no indication of where it came from. Seems to be concentrated to the rear of and on the rhs of the rubber heel pad near the throttle pedal.

If anyone else has had this problem and can help I would be most grateful.
 
the horseshoe/clamshell, the cover that is behind you that raises when you put the roof up/down, there is a foam insert in there that also has some drainage holes at either side, this foam is easily dislodged and gathers lots of debris
 
Thanks for that. I must admit I haven't checked around that area yet but I will. I doubt that it is the area where the water gets in though, as the carpet to the sides and under the drivers seat is dry. Still I'll live in hope!
 
Just in case, have a look here, this also shows the clamshell bits

That's a lot Elliot, I know what I will be doing tomorrow (provided it's not raining).
I rechecked the area behing the drivers seat, and sure enough it was soaked, so it looks loke I have two problem areas. I can't inderstand how the water would get from behind the seat to the front.
If I succeed in stemming the flow I'll let you know.
