edgy Posted 27December, 2018 Report Share Posted 27December, 2018 Hi, We recently acquired a 97 986 Boxster, put some hours on it for the first time yesterday and due to the heat, ended up with the top on most the drive and AC blasting, which after some time ended up splashing on our feet (both sides) condensation, when you take a turn, you hear the water sloshing in what I'd imagine is the evaporator housing? My first thought is the drainage tube is blocked and needs cleaning. thoughts? Link to comment Share on other sites More sharing options...

edgy Posted 27December, 2018 Author Report Share Posted 27December, 2018 Ok, So i left the office early today and had some time to look at it.. I pulled the underbody tray out and then proceeded to look for the tube, I couldn't find it. I read a post online that suggested its best to attack from the inside, so away I went, the carpet was soaked on the passenger side. Upon pulling it apart, I noticed that the foam backing on the carpet was in pieces and coming away from the carpet underside, evidently this has been an issue in the past where they have had to get to the drainage tube or something, what I did notice is the grommet that fixes it into the floor was dislodged, on the underside of the grommet it is actually a one way orifice, a rubber flap. I think this was dislodged because the way the thick carpet foam is moulded, it protects the tube from being kicked out of its place, the fact my foams are shot, means its highly likely at some point it has just been dislodged by the passenger. Now, it doesn't appear to have any fixings that would secure it? I have attached a couple of photos, I am wondering if anyone knows the answer to this? I'm sure its probably very similar to the 996? I did add some cable ties to every joint to help secure the rubber connectors to the plastic hose. Also, I fired it up, took it for a 20-30 minute run, including leaving it running with the AC cranked in the driveway and it seems to be ok. Few hot days ahead, so a good opportunity to leave it out to dry! Cheers Link to comment Share on other sites More sharing options...
firstone Posted 27December, 2018 Report Share Posted 27December, 2018 Seems like you've nailed it. The tube really should have a couple of fixings. 3M have some very good double sided tape fixings? Link to comment Share on other sites More sharing options...

Alright, I have finished it today, heres how it went: Pulling back my carpet, you can see that in order to be able to do this, without removing the entire carpet, they carved off the foam backing Placing all the pieces back in, I was able to work out where they all went from the witness marks underneath them. As you can see here, my suspicions are true, the moulded foam protects the drain tube, as there is reliefs underneath it. Once all the pieces were in their places, I did a test fit and then applied spray adhesive so they would bond to the carpet again! Some wood from my smoker to weigh it all down... Then viola, all cleaned up good to go! Test drove it for an hour plus today in the heat with it cranked... no dripping inside, and the drainage runs out underneath again.
