As per title, my IS250 is a nightmare for misting up inside and it’s driving me mad. No sign of damp or leaks anywhere and I’m not losing coolant, no smell of damp either.
The aircon has got a leak as I was told in the summer when I went to get it regassed but I don’t think that is the issue?
It makes no difference where I set the heating controls to hot, cold outside air in or to recirculate the car mists up like crazy.
Now I was advised to change the pollen filter which I will do, but removing the filter it was pretty much spotless although I’ll replace it anyway. What I did notice when changing it however was that it didn’t move at all when I changed the heating from outside to recirculate, the filter stayed put.
Could this be the issue?
