All Windows Fogged??

Man, I don't understand this.

Lately, last 3 or so days, everytime I get into the car all the windows are fogged from the inside. Not sure why...

99 Boxster. I live down in Mobile, AL and we have been getting alot of rain. I don't feel any wet carpet so I'm thinking there isn't water in the car but heck if I know...

Any ideas guys? I'm waiting for a warm day to drop the top without rain and make sure everything is dried out.

edit: has been fairly humid out and I am going out to check drains now.

Well, I went and checked both drains in the back, one on each side behind the seats...Not clogged or any standing water. I also checked both drains in front next to the battery...No standing water or clogged.

I did notice a little residue around the top of the back hatch where the seal is for the oil and coolant so I might order a new coolant cap in hopes that fixes that issue. I had to add about a quart of coolant over the last 2 months or driving 2 weeks ago. It still looks 99% full in comparison to what it was 2 weeks ago.

+1 on leaky heater core, since you have had to add a quart of coolant. See if you have any drops of liquid near the gas pedal and/or on the equivalent spot on the passenger side.

Much easier DIY on the Boxster than just about any other car. You can access it and change it from outside the car, at the base of the windshield.

If its the original top, it maybe porus. Spray a couple of coats of scotch guard or raggtop sealant. Don't get any on the plastic window or body. Top should be dry and clean before applying spray.

Hey man, I live in Florida and get the same problem. It's basically humidity and a temperature change from inside and outside of the car. During the summer mine hardly ever fogs, but this time of year, expect it. The scotch guard is a good idea or any convertible top repellent works. Need to do mine soon too. JB

Quit trying to have sex in your car, take a blanket!!

Fog is usually a moisture/temp differential. take a paper towel and see if there is water gathering anywhere else, under seats,under floor matsback window area..... Check under your convertible top where it goes down into the boot thingy also. Do you keep your car stored outside? Moisture might be in your air ducts also. It might be climate also. I second the scotch guard on the top idea!!

Set your HVAC controls to bring in fresh air. Don't recycle your cabin air.

If it smells sweet... heater core.
