Have Moisture In My Boxster Any Way To Rid It?

[ajsimon85]

I think the prior owner of my Boxster convertible might have taken a small amount of water in the past at some point due to not clearing the drains. The drains are clear now and I don't feel any wet rugs, or backseat rug. I do see some fog on a small part of the window sometimes. Any way to fix this issue?

Which window? Front, rear, side, all? Where you are seeing the fog has different possibilities. Like if it's the windshield it could be a weepy heater core about to go. Also look under the seats, from what I have read in the past Boxsters like to puddle up as there is like a little well under the seats. Drive side is the worst because there is a module that when wet can cause all sorts of issues with power windows, anti theft, etc. It is easy to remove and check if you are are curious.

Slide each of the seats forward and lift the back of the floor carpet. Feel the padding underneath. The padding is about 1" thick foam that acts like a sponge. The carpet can feel dry while the padding remains soaked.

The best way to dry the padding is to remove the carpet and let it air dry with a fan or in the sun. I don't like to pull the whole carpet out. What has worked good enough for me is to remove the seats and the gas pedal, then prop the carpet up with some wood. Circulate air underneath with a small heater or fan. It can take two to three days to dry.

***If you turn the key while the seats are disconnected from the wire harness, the airbag light will need to be reset.

***If there is moisture in the electronics box under the seat, it can cause failure of the immobilizer, locks, and windows. Best to check it, make sure it is dry and not starting to corrode. Even when the corrosion has started they can often be saved.

Does the moisture appear when driving or just sitting in the garage? Temp fluxuations can cause condensation on just about any surface, glass, metal etc. If it happens while driving when damp and cold try running your heater with the A/C compressor on, it will help dry the air and is normal. If it is getting condensation while sitting, you may indeed have moisture trapped somewhere. I keep my windows down about 1 or 2” when parked in the garage. It allows air to circulate a bit and keep excess moisture a little better controlled. A garage has wild temp fluxuations and humidity ranges depending on climate. Looks like you are in New Jersey, might be worth considering a dehumidifier in your garage, or secondary heat.

Do you park in a garage? If you do, you might leave the top down when it's inside. some heat might help, too.

A little condensation in a damp, cool climate is normal, tho. It's why the rear window on the glass tops has a demister and the wind screen has a defroster. Probably the worst thing you can do, regarding this, is to leave your convertible out in the snow or spring rains.

We don't have these problems around here, tho.

I had to use a shop vac on one boxster -- the amount of water the backside of the carpet (pad) can contain is impressive.

In stead of sandbagging for floods -- I'm just going to collect Boxster carpets and place them around my beach house.

Get a product called Damp-Rid. You can leave the absorbent crystals in the container on the floor. The crystals absorb any moisture, then you dump it out. Refills can be purchased. They sell these at most hardware stores and big box stores like Loewes and Home Depot.
