Tricky-Ricky Posted September 6, 2008 Share Posted September 6, 2008 Just wondered if anyone else has had this problem, its only happened about three times so far, and only in heavy rain, and i am inclined to think that its down to the air con not coping with the sudden change in temperature of the screen, i just get sudden mist up and have to keep wiping the screen until everything catches up, which sometimes takes a few minutes, which is a bit worrying on the motorway:( Quote Link to comment Share on other sites More sharing options...
Havard Posted September 6, 2008 Share Posted September 6, 2008 How's your heater matrix?? Quote Link to comment Share on other sites More sharing options...
Konrad Posted September 6, 2008 Share Posted September 6, 2008 Switch to open circulation (from outside of the car). When the cycle is closed, there is no chance to demist windows in the car Quote Link to comment Share on other sites More sharing options...
Ben-san Posted September 6, 2008 Share Posted September 6, 2008 The aircon should be condensing the moisture in the cabin, but I'm unsure whether this depends on recirculating or not. If there's sudden misting despite it being on all the time, my first action take it to an aircon fixer-upper. Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted September 6, 2008 Author Share Posted September 6, 2008 Heater matrix seems fine, this only happens with heavy rain, and i have tried the non re-cirque switch, the only way i could get it to demist was to turn everything up full, and even then it took its time, the rest of the time it seems to work as it should:blink: Quote Link to comment Share on other sites More sharing options...

That will demist all interior glass very quickly. Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted September 7, 2008 Author Share Posted September 7, 2008 Glad I'm not alone, seems to me that the system is not able to cope with very rapid changes of temp. Quote Link to comment Share on other sites More sharing options...
