SOURCE: my demister in rear windscreen not working

Do you have rear window tinting?( the plastic sheet type ) If so,check that the edges over the demister tapes have not curled up pulling the tapes off the window and diconnecting them. If they need repair, a small bottle of tape repair solution should be available from a spare parts retailer.

2015 carens, its either front windscreen demisting OR car heating, but I need both. How to fix?


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?

My heater on my peugeot 307 doesn't demist windows but the heater and everything els work


I'm guessing that no air blows out of the upper vents when you select the demist setting? There are numerous flaps in the air conditioning systems on automobiles that move to control where air flows. Chances are one of those has either failed or the actuator has broken. Depending on your level of skill you may be able to rig the doors into the correct position without removing the dash. A complete repair will probably involve removing the dashboard and replacing the failed component.

No vacuum at air con vent control knob in vu commodore


check small vacuum hose on rear of square inlet manifold top that goes throught firewall ( bulkhead ) is not cracked or has come off
it goes into cab near heater hoses. this is the vacuum supply hose
if you have no vacuum the heater controls default to go to windscreen. also check the black & white plastic little round one way valve for leaks & operation
also check vacuum hose that goes onto heater tap that is in right inner gaurd under brake master cylinder area for leaks and that its on the heater tap valve
if they are all ok check inside do you hear any hissing noises behind dash controls or down at front centre console area?

2006 x type saloon demist function does not work floor and other outlets o.k


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!

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.

Have you taken the dash apart and checked the cable on the switch? Or tested the switch if it's electronic?
