Condensation on the inside overnight
Overnight temperature here in the UK is freezing and below. My '98 GS300 has quite severe condensation on all windows overnight.
Has any of you guys encountered this and come up with a solution?

A quick Google search:
Condensation happens when there's a difference between the temperature and moisture levels inside and outside the car.
The car is a closed environment in which dampness and heat can build up (heat holds more water).
When this moisture meets the cold windscreen it changes from invisible vapour into water droplets, which stick to the inside of your glass and impede vision.
Simply breathing inside a car is enough to start the process.
Don't leave anything moist in your car. Check the boot really well,i.e., under carpets, wheel well,etc. Check your inside carpet for moisture-don't forget you may be tracking in snow-. It's a 1998 car, so you may have a leak in doors, windows, sunroof, windshield, ...
Lastly, don't put the air cond. to recirculate, leave it, even while parked, to draw air from outside.
To see what's going on at night, get one of those home electronic thermometer/hygrometer that have an outside sensor. When you park your car at night, place the base unit on the hood, roof or boot of the car (let it be uncovered so don't put it under the car) and the outside sensor inside your car.
One last thing, have you noticed one window or side of the car more foggy than the rest?

Have you been using the fresh air intake, or recirculating? Automatically, it should be using fresh air intake for heat, but if it isn't, that will cause condensation on the inside.
Leaving a window open a tiny bit can help prevent the windows from frosting up on the inside but mainly you need to keep moisture out. Carpeted floormats take forever to dry out if they've been soaked, they can be a source of a lot of moisture that will condense on the windows.
