Condensation rx450h

[granadaman]

Have got heavy condensation on windscreen does anybody else get this, car doesn’t have a sunroof and all carpets seem dry, it takes an age to clear it before I can drive off, at a loss as to what causing it.

Ensure the screen is very clean inside. A dirt film attracts water vapour and allows it to condense on the surface.

Check the condition of the cabin filter(s), check the underlying floor sound deadening is dry. Keep the a/c switched on permanently, this dehumidifies the air.

I agree. Always have aircon running and never have issues, although my car is in an enclosed car port at night.

Yeah check cabin filter, I had same problem, changed the filter and the problem has completely gone

Also check and make sure the ventilation it isn’t stuck on recirculate.

Isn't that what most people call a garage Les?

Cabin filter changed at last service 4000 miles ago, screen was cleaned 1month ago and car only used at weekends, I don’t think it’s stuck on recirculate as it never steams up when car in use, if it’s under sound deadening where’s it getting in as no signs on carpets. I’ve never had a problem with not using ac on other cars I’ve owned, wife’s car is a Kia ceed she keeps it like a crap box never cleans glass at all and her car has no condensation on inside at all anywhere.
