Windows misting up

[cpu_man]

Hi chaps, not had a chance to look at my car yet but thought I would ask incase it's a known thing.

I have noticed over the last few nights my NSF,NSR and windscreen will fog up overnight where the inside of the glass will be wet, damp etc? But only them windows.

My xc90 has no sunroof so would it still have the drain pipes down the a pillar?

Any known issues?

Regards

Ditto but I'd put it down to a wet brolly, coat, dog blanket/towel/water bowl evaporating
It does seem to be worse this year though
In the past I've put one of these in one of the boot side storage caddies which helped

This wasnt the actual one so check the size first
Hope it helps

Prevailing wind direction?

If those window surfaces are cooler than the others any damp in the car will condense on the cooler surfaces.

Could try turning the car round and see if the condense moves

Cheers

Used to be a common occurrence but much less so with modern cars with A/C as that dehumidifies the air. However a/c systems do not run below around 4 or 5 degrees due to the risk of the evaporator icing up. So if you get a sustained period of lower temperatures, the dehumidifier function does not operate and the inside of the car absorbs more water.... and hence more condensation.

When was the last time the pollen filter was changed? ... an old damp filter can also cause this type of misting-up.

Hope it helps.

Did you leave anything wet or damp in the car?
If so, take it out and dry it in the house

I have a boot rug that gets wet from melted snow after a day out in the mountains.
I always take it inside to dry out overnight and put it back in the car dry.
Helps to prevent mold and musty smells and dampness.

so check the boot and back seat for anything damp...
