Trapped moisture in car

Has it got a pollen filter?

Leaving a window completely open around sunset will help, but may not be enough.

There's water leaking into the car. Check the drain holes in the bottom of the door/drill some new ones. Check the seals, especially the boot. Also, the light clusters.

Also look for the drain holes at the bottom of the windscreen under the bonnet. They often get blocked with dead leaves etc.

£-land do them. also have you checked the sunroof drains in the corner of the sunroof (front), you will need to pull the roof lining down to get a proper look, but I've seen a few that have rotted where the drain & drain tube meet.

Good tips, thanks. The sunroof drains seem OK. Some rust holes in the boot, I guess that's the problem.

My Cougar was doing this. I changed the pollen filter. It stopped doing it.

I don't think the water is draining upwards through the floor of the boot, but that may indicate that water has sat in the boot for some time. Is the boot carpet wet?

I don't think there is one, but will check. I'm ready to be proved wrong!

Yes, and smells failty mouldy. The main source of the mouldy smell however is the rear seat. The base of that got wet sometime and the spongy material inside is exposed underneath, with the obvious consequences. I don't have anywhere I can remove and store it (Tried the kitchen overnight but management wasn't impressed!) so I guess I'll have to deal with it some other way. If I can.

Once you have stopped water coming in, the car will dry out quite quickly - assuming you drive it a reasonable amount with the heater on.
