So the rear door windows only somehow gather humidity, they don’t necessarily fog up, they just have those droplets of water in that specific spot, as seen in the picture. This happens all year round, but even more during autumn/winter due to the outside humidity.
There is no leak, so it’s not like water would drip there. The droplets are caused by condensation. On the other door there is even more condensation.
I have disassembled the trim at one point to see if I could prevent it from happening again, but nothing changed.
I also tried putting a small silica gel packet near the spot to absorb the moisture, but it didn’t really help.
Did anyone else encounter this problem? Or maybe have some suggestions on how to fix this?
For condensation to form the surface has to be cold and have warmer moist air the inside touching cold glass.
When it occurs depends on relative humidity, glass & air temps.
Think ice tea glass the outside sweats which is condensation.
So where do you live?
What is outside temp?
What is inside temp?
Do you have AC or heater on?
Check to ensure no air vents pointing on it like from rear seats or those little vents they put to defog windows.
Down here in south we can get that on super humid days with AC pumping but would be on outside
Happens on inside in winter when cold out but was humid so plenty of moisture in air.
Happens more when ambent outside weather air temps changes a lot very quickly like say goes from 70F today down to 50 tonight.
You have water intrusion from somewhere, check ventilation system for water, check sunroof drains and door drains, where are you located? If it's not raining in your car then the water is evaporating from somewhere and is creating the condensation on the windows.
YGMN's questions are good ones
