I don't know. I am open to suggestions. I have spent a ridiculous amount of manhours on this stupid water leak! Im exasperated... The 3 f's are setting in...fatigue, frustration, and f@&k!!!

I finally got round to investigating this, we'd had a fair bit of rain recently and before that I'd totally dried the car out, sure enough moisture in the footwells running down from the HVAC box, with the source being water pooling behind the firewall.

I felt under the scuttle and yup the washer jets were dripping wet, since water doesn't flow uphill this must be the issue, only took 5 years to figure it out!

I lifted the nozzles out cleaned and dried and used some non setting sealant on both sides of the (fairly crispy) gaskets.

One other thing I found was that the washer hose was a little loose on both washers, this may have contributed to the leak, so I trimmed back the hose added some blue hylomar to the barbs for good measure and fitted some new porsche style hose clamps.

I took the car out for a nice long run to warm her through, fingers crossed it stays dry. I have an Air Dry in the frunk and another in the cabin to help mop up residual damp, and hopefully eventually I'll even get all the damp out of the instruments so they don't mist up anymore!

Same problem here too. Solution was a garage.

My passenger side rear footwell is where I would notice the water. Another possibility to check- I think that the frunk floor has a straight shot into the interior. So water in the frunk will rush into the interior foam the first you accelerate.

Anyway, good luck!

I replaced the washer nozzle gaskets and i think i solved my problem. When PO had car repainted they never replaced gaskets. We had long hard rain and it was dry when i checked the next day!!!

I had tremendous success with the approach outlined in post 26 of this 993 thread.

Leak Chek is not available thru retail that I could find--direct sale only. I used an equivalent product from O'Reily and it did the trick.

Great thread that, Leak Chek sounds handy, I'll remember that but I loved the name "Capt. Tolley's Creeping Crack Cure" I had to buy some, not sure what I'll use it for...
