Windscreen demister the dash switch for windscreen does not work and i need to direct air/heat to the windscreen???

If you set the temperature to a high temperature when demisting, it should still provide heated air, just not through the dash vents aimed at you. Is that not sufficient? Does your car has seat heaters?

Sticking defuse doors or control panel not making connections

What car?

Turn setting for window demister off , air con comes on automatically on some vehicles when windscreen demister is on

Hi this could just be a faulty switch,especially if it's the origional one.

the demist function should be for the windscreen. the a/c should kick on and put out heat at the dash vents. the combination between the a/c and the heat allows the system to evaporate any moisture in the air allowing it to warm you and evaporate any moisture on the windscreen, and anywhere else they may have it duct to so that vision is not impaired. enjoy!

pull it out and have a look something is stuck like some sort of gate mechanism ,,, what or where havent a clue but something on the operating controls isnt lifting a lock of some sort off .well its a jaguar and they can be just like a woman ---awkard to say the least try polishing it and cleaning the interior and rubbing some leather cream into seats then i bet it will cure itself .

may be just a cable adjustment.


SECTION 412-01: Air Distribution and Filtering 2001 Focus Workshop Manual DESCRIPTION AND OPERATION Air Distribution and Filtering The new heating and ventilation system ensures even air distribution.
The temperature control and air distribution flaps are controlled by two operating cables. All vehicles have a recirculated air function, with the flap controlled by a servo motor.
Air is supplied to the windscreen and side windows regardless of the air distribution setting.
The clean air filter is fitted as standard in most countries. This cleans the incoming fresh air of pollen and dirt particles. It must be renewed after every 40,000 km under normal operation conditions, or after 20,000 km under difficult conditions. If no clean air filter is installed, a plastic grille is fitted over the air intake. This can easily be replaced with a clean air filter.
Air distribution operating switch
Face level The main flow of air enters the passenger compartment at face level.
Face level/floor level The main flow of air enters the passenger compartment in equal parts at face level and floor level, and a small amount flows to the demister nozzles of the side windows.
Floor level The main flow of air enters the passenger compartment at floor level, and a smaller amount flows to the demister nozzles of the side windows.
Demist/floor level The main flow of air enters the passenger compartment in equal parts at the windscreen and at floor level, and a smaller amount flows to the demister nozzles of the side windows.
Demist The main flow of air enters the passenger compartment at the windscreen and a smaller amount flows to the demister nozzles of the side windows.
Air distribution operating switch Air distribution operating cables
NOTE: The Bowden cables for LHD and RHD vehicles are identical. However, they are fastened to the air flap operating mechanism with the respective reverse side of their connectors.
The air distribution switch operates with two Bowden cables. The cables operate the air distribution valves in the heater housing.
To remove and install the cables, the rotary switch must be turned as far as it will go to the left. The air flap mechanism engages easily in this position, making the installation of the cables easier.

EASY FIX HAD SAME PROBLEM WITH MY AUDI A4 2002 JUST LAST WEEK.....WILL BE ONE OF THE CONTROL MOTORS FOR AIR FLOW...UNSCREW THE 4 OR 5 SCREWS THAT HOLD THE GLOVEBOX IN PLACE TAKE CARE TO UNPLUG GLOVEBOX LIGHT WHEN LIFTING OUT...NOW YOU WILL SEE ALL THE CONTROL MOTORS RIGHT-HAND SIDE OF YOU...EACH ONE CHANGES THE AIR FLOW ...THE ONE FOR THE WINDSCREEN IS THE ONE NEAREST TO THE FRONT OF THE CAR..UNPLUG THE WIRING CONNECTOR UNDO THE 2 SCREWS NOTING HOW THE MOTOR SHAFT ENGAGES...EASY....IF YOUR UNSURE WHICH CONTROL MOTOR IT IS TURN ON YOUR BLOWERS AND TEST EACH ONE..SIDE VENTS, DEMISTER,ETC...TRY AND GET A SECONDHAND CONTROL MOTOR FROM SCRAP YARD...DEALERSHIP PRICES JUST A JOKE.. FOR A CHEAP TINY MOTOR NOT MUCH BIGGER THAN A MATCH BOX OVER A £100 SCRAP YARD £5 POUNDS...........HOPE THIS WILL BE OF SOME HELP TO YOU...
