You have a loss of vacuum from the engine check the vacuum lines to the vacuum storage canister under the hood. If the vacuum form the engine is ok check the lines to the control head in the dash one may be pinched or restricted or the vacuum switch may be faulty and leaking.

SOURCE: Faulty Fan Heater - The main vents are just blowing out cold air.

Go to your idrive., climate the vent settings. you will see a person along with vent areas on the side.
If this persons color is blue it blows cold air so turn the dial for vent closest to that person until the
color changes red then hot air comes out on the vents for driver and passenger. Then let me know.

SOURCE: heater/ac door actuator isnt workin right. air

Sounds like either the computer that controls the auto climate control has gone out or you could have a vacuum leak. I would definitely check the vacuum leak first. I took my 98 Lesabre to a repair shop several years ago for the same problem. When I picked it up they told me my computer was out and it would cost around $600 to fix. As an alternative, they had unhooked and rerouoted vacuum lines, breaking a tube off the controls under the right side of the dash. They told me that they would have to remove my glove box each spring and fall and reconnect the vacuum lines to change the airflow from floor to dash and vise versa. My fix was to run the lines under the dash just beneath the ash tray and connect shut off valves to the vacuum lines. Now when I need to use the AC I can change the flow of the vacuum by simply turning these two valves so that the flow changes from floor to dash or back. I know this is pretty jack leg but the damage had been done and this has actually worked pretty good.

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?

EF 1995 Falcon can change the vents on the knob heating control


I don't have repair info for cars sold outside of the US, but in general terms you would check the blend doors under the dash for problems.
They may be vac or electric controlled. The blend doors direct air thru the heater core and thru the vents.

2001 ford focus defroster blows out ac vents


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.
