Every time it starts to rain all the windows get super fogged up. I turn on the heater so the windscreen defogs and I'm able to see the road but I can't see anything from the other windows. Does anyone know a way so they won't fog up so much?
 
I use some antyfog spray and it works if i am only one in car. But if rain is longer than rear Windows get fogy anyhow. Front side Windows eventualy get clear.

If car is full (4 persons) nothing is helping.
Only real help is microfibra cloth.
 
In fact, if the car is full it's easier to keep the windows clear, everyone wipes his/her window, plus back seat passengers wipe the rear screen - heated screens on later cars don't usually work :-) . Reminds me of my early R4 years...
 
In my opinion problem seems to be worsened from the fact there is only air-INlet and no OUTlet. I removed the rear reg.plate drilled some holes
through tailgate then "bent" or angeled the holes by pushing in the drill and bending it down from outside so no rain runs in via holes all behind the reg.plate so not visible from outside after mounting reg.plate back on.. This seems to help humid air to be sucked or pushed out...
-Other option is to stop breathing inside car :whistle: -R.
 
oh my God, R(enaulst)4 are not ment to be driven in a foggy weather, electrics fail when moisture is between 70...100%
last week i enjoyed non working turning signals, nothing helped untill relatively moisture levels were down to 70%
