Default Carpet soaked on passenger side, how to remove?

Trying to figure out how to lift up the carpet on the passenger side footwell as it is soaked. I'd rather not break any trim pieces so are there any hints on how to do this without tearing up my interior?

I cleaned the drain line about 2 months ago but just this weekend it started leaking again. Not sure what the issue is but I need to dry out the floorplan before proceeding.

Thanks!

I figured it out. Didn't have to remove any trim or anything. Just had to be careful.

Unfortunately the A/C drain plug wasn't functioning even though I had "fixed" it before. I ended up cutting the little flap now it's draining as it should. Have a fan on my carpets now to dry things out.

On my '06, I could pull out the outside edge of the carpet (from under the door sill and the passenger sat kick plate) and then prop it up with something while it dried. It helped it dry much faster if I used towels to try to get as much water out of the 2" of foam-rubber glued to the back of the carpet. The foam rubber works like a giant sponge. You might notice Porsche gave us a little removable section of carpet so we could inspect for water on the 958 (can't think of any other reason for it) without having to pull the carpet out.

There are other possible leak sources worth looking at - and I'll just briefly mention them (they've been covered in other threads):

1. AC drain - you've done

2. Sunroof drain - when plugged it overflows, dribbles on the inside of the headliner, then runs down the inside of the "A" pillar, past the fusebox and behind the passenger side kickplate to soak the foam rubber under the carpeting. This is rather common. Cleaning them is tricky since there are some junctions and right angles in the drain lines (mostly behind the right side fuse box).. I've used weed-wacker string, and compressed air. The outlets for them are located behind the wheel liner - and are known to plug - they're fish-mouth sort of outlets. Most smart people remove the fish mouth and just let them drain unhindered.

3. Firewall leak. The windshield drains right down around the hood hinge on the passenger side. Unfortunately - it tends to carry along with the water any dirt or leaves or general munge from the windshield area down that drain. That drain is funneled down around the hinge and down through the chassis between the inner fender liner and the outer fender skin, to emerge at the end of the fender right next to the front edge of the door. A LOT of dirt can accumulate there. Removal of the fender liner will let you clean most of it out.

Also - on my '06 - there was a 1.5" round hole - obviously for wires for another model - right where the fender inner wall met the firewall. I found it using a MAG light and looking very carefully. Using the MAG-Lite I could see the wiring harness inside the passenger compartment. The water from the windshield went down that far, filled up the area and then flowed right into the interior of the car behind the right side kickpanel. There was a "high-tide" mark of dirt even with the bottom of the hole. Cleaning up that area (compressed air and LONG tweezers) and then installing a plastic body plug in the hole ended that source of leaks. I have heard of an unsealed seam in the body on a 958 in this same area - so it's worth taking a look around. I know there is a drain in the bottom of the air intake for the heater - but it's not simple to get to since there is a water catch tray that doesn't seem to want to release. I could just see the hole with my MAG-Lite and I poked down into it about 8" with a 24" long 1/2" tie-wrap. I saw no sign of water being trapped in the area.

So far my '11 CTT 958 has remained dry, I hope that continues. Being parked in the garage likely helps. Not as much tree-crap gets washed down into the drain passages.

Please update us with what you find. BTW - for the AC drain, you can pull it off the inside pipe on the bottom of the heater box (remove the panel under the glovebox and prepare to get a headache doing it) - and then poke crap out of it with a long screwdriver.

Are the sunroof drains maintenance issues for both types of sunroof (small one over front seats and Pano-roof)?

No issues blowing drain hoses off of fittings when using compressed air to blow-out drains?

Do 957s also have the same fish-mouth fittings at the drain outlets?

957s do have the star shaped grommet plugs in the wheel wells. There was a service bulletin about removing them completely. Good to check them yearly or more often if you park outdoors.

I'm not sure how or why but the A/C drain that plugs into the firewall must have been blocked or just not working properly. I had removed it before and it appeared to be fine but this time I snipped off the little rubber flap to make sure it drains properly.

I tested it and immediately saw a puddle coming down when turning on the A/C.

After pulling the carpet up and vacuuming it as much as I can I ran a fan on there overnight. It seems pretty dry but I'll also put a dehumidifier in there to make sure. Also I found my pollen filter was soaked so I had to dry that out as well. Funny you mentioned the little "window" into the carpet as that is exactly what I used it for. That's when I knew I'd have to pull it up to dry it out.

I haven't checked the sunroof drains yet but this vehicle is always garaged so I don't think that's the issue. Plus I clearly saw where it was leaking and it was the A/C drain.

I'll keep an eye on it and make sure this really is it. What a hassle - it really upset my wife as she didn't like seeing water pouring into her daily driver.

I have a pano and did locate where the drain is but since we didn't have rain yesterday and it was leaking I knew it had to be something else.

Mine is a 958 and it still has those so I cleaned both of them out. There was some debris in there but not enough to stop the water completely. That's why I was surprised this was an issue as I made sure to do that after Fall just in case leaves got stuck in there.

Shoot some compressed air in the ac condensate vent. Had the same problem last year.

I had that problem when I got my 05CTT. I could not for the life of me get the AC drain to re-seal (someone had been in there before and also could not seal it - which is why the floor got wet) But you need to make sure that water can't come back inside. I took a nice length of heater hose and made it so it just fit the hole but also hooked into the evaporator housing. Sealed it with a fair amount of black RTV, and it hasn't leaked since. Took a week and a half to dry that sucker out - maybe longer.

My dealer cut off the drain pipe flaps that were there to stop insects from crawling into the car from underneath the car when parked...
