artscot79 Posted November 6, 2014 Share Posted November 6, 2014 the aircon is set to windscreen if its on this it will come on automatically the rear window on any car isnt quick to demist and doesnt sound abnormal 1 Quote Link to comment Share on other sites More sharing options...
SeanW Posted November 6, 2014 Share Posted November 6, 2014 If you do run the AC to demist it does help the back slightly as it dehumidifies as it runs. Granted, if you've a full load of soaking wet adults it makes naff all difference. RainX anti-fog can help a little - but I wouldn't say it's fantastic Quote Link to comment Share on other sites More sharing options...
Johna456 Posted November 6, 2014 Author Share Posted November 6, 2014 my last focus an 03 estate the rear windscreen cleared with in minutes i still think there's a problem shouldnt take 20 mins to clear with just me in the car, the heated front windscreen don't work either Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted November 6, 2014 Share Posted November 6, 2014 Is your battery good? I know the front screen wont work without a good battery. Could explain the poor rear clearing as well if the voltage it's getting is too low. Quote Link to comment Share on other sites More sharing options...
artscot79 Posted November 7, 2014 Share Posted November 7, 2014 It depends it can take 10 mins to clear a rear window if its cold enough or you could have water getting into youre boot.as above if the battery isnt any good or the wrong type the front screen will not work Quote Link to comment Share on other sites More sharing options...
Dee_82 Posted November 7, 2014 Share Posted November 7, 2014 ive noticed that it seems to take ages on ford cars, my focus and my partners festa both take an age to clear the rear compared to other makes ive driven, im guessing its a ford thing as the fronts, even without blowers on, demist really quick Quote Link to comment Share on other sites More sharing options...
Johna456 Posted November 7, 2014 Author Share Posted November 7, 2014 possibly right about the battery, i had it in garage a month or so ago and they said battery is low and on it's way out. will get a new one and see if it makes a difference Thanks chaps Quote Link to comment Share on other sites More sharing options...
theduke Posted November 10, 2014 Share Posted November 10, 2014 May be worth checking the connections to the rear screen one of mine had came loose and melted then stopped working easy to check just need to undo the torx screws in the door handles in the boot and the rest pop off....could also check for voltage there too just incase its battery etc Sent from my phone using Ford OC mobile app Quote Link to comment Share on other sites More sharing options...
