Rain entering cabin

[Need_for_speed]

Walshie, here's another thread -- water entering via the side mirror, running down the wire harness through the bottom of the door and into the footwell.

You would only have water building up in the a/c drain if the a/c was running. I don't think this is the problem.

Good luck my friend!

Thank-you, need for Speed for all your help. I will investigate further and post my findings.
Thanks again

To get to the bottom of this you really need to pull the carpet out. The backing is about 2" thick foam. This absorbs and retains water. You might think it is coming from the front but I could be anywhere.
To pull the carpet the seats and centre console need to come out but once you have a bare tub you can dust it with talcum powder and then follow the tracks to where the leak is. This also gives you the chance to get the carpet dry. You won't otherwise. Even leaving the roof down it will stay damp. Trust me on this.
Tracing water leaks is tough. The Boxster isn't designed well to keep the rain out but if you take your time and trace and seal the leaks you will get this.

Thanks I am off work this week so I will set about it. I have to re colour the leather so that would be a good time while the seats are out.
I will post result

At last it looks like I have found the point of entry for the rain water. After extensive stripping out and water testing I have found water coming in around the lower extrusion of the heater box as it passes through the bulkhead. I am not sure what is on the frunk side of this but I think it's going to involve shipping the dashboard out to re seal it. Has anybody else had this problem.

Walshie, Did you ever get this sorted? The passenger footwell of my '97 Boxster gets soaked similarly to yours, and today I sleuthed out the pathway as you describe here. Have no idea how to fix it. The drains in the frunk work just fine, but regardless there is seepage around the bulkhead pass-through grommet or seal that goes to the heater box under the dash. Would love to hear how you solved this!

Thanks so much in advance if you don't mind taking the time to share!

Hi Scott
Yes I did
The water was coming in through a blanking panel bonded to the bulkhead on the passenger side. I had to remove all of the dash and centre console. I then had to remove the heater box assembly complete to get to the panel. I then re bonded the panel with Wurth bond and seal and for an extra measure, I then applied dynamat to the whole area before putting the carpet back. It never leaked again

Thank you! And--oh my--it sounds like a ton of work. How long did it take you to do all that? I clearly have some research ahead of me in order to get it right. Have recently done the center console so not worried about that, but the entire dash seems another thing entirely...

Thank you so much again, and cheers!!
