How do i dismantle the dashboard


Presuming your car is fitted with the automatic heating/cooling system.
There is only one fan controls the heating/cooling system the distribution from this to the various vents is controlled by a series of electronic flaps which open or close dependent on the temperature selected at the control unit.
If the motor is running and the drivers side is receiving cooling it may be a problem with the control unit or a flap has stuck open.
Replace the control unit first as the flaps are a citroen job.
Control unit is the bit with the temperature displays etc.

VW Phaeton 2004 model 5.0 litre V10 diesel has developed a heating problem whereno heat enters cabin despite heater controls in hot position.


My guess the heater flap controls are not moving the flaps.
Look up beside the heater unit while someone operates the controls.

Fresh air intake door for cabin slaps back and forth several times before settling into position. Recirculate position makes no noise, just fresh air position.


my guess> , seeing as Im blind and most answers , not hands on and blind are totally a waste...... ask your mechanic.
the cable clamps fell off the cable driving this flap and is now loose.
the cable provides natural friction to prevent this.
but id have to , look.

Check the blend door cable for proper attachment to the control panel and to the blend door. Try opening the door manually to see the you can get hot air out. If not, the door may be broken inside the heater box. If yes, correct/adjust the cable attachment for proper operation.

2004 dodge 1500 cabin air filter


the cabin air filter is located on the passenger side of the cowl. after opening the hood, remove the windshield wipers and the black covering ( 2 small T-30 screws, and a few body grommets). after you remove the cowl there will be a grey accordion looking filter in the cowl, remove that and replace with the new filter.

My 2011 porsche cayenne s is giving me heating problems, more specifically the distribution of heat throughout the cabin when choosing more than one zone. When I want to heat my feet only, it works fine....


All the actions that are made from the control switch are vacuum actuated and you very well may have a vacuum lien off or crimped from the switch to the blend doors/flaps. Though it may be a common problem with these vehicles, it is not "normal" and can be repaired.

Hot air forced into cabin while driving 92 saab 900


the air distribution switch controls the air distribution and the fan, distribution switch in the 0 (straight down position) will be off. Car movement forces air into teh body, but with teh fan off there will be no air when the car stops. Does the fan run when the distribution switch is in any other position? it should respond to the speed settings of the fan switch.

There is a vacuum bottle accumulator that assists the distribution switch, sometimes this gets disconnected and the switch settings don't work.

Do you hear any noises if you turn the distribution knob while the car is running? suction noises, or flaps opening?

If not, then you likely have a vacuum problem (check for a white bottle in left front wheel housing, except convertible -> under the spare wheel, tank should have one or two vacuum lines connected to it (one for convertible). A disconnected or leaky line is the most likely cause.

Possible other causes are faulty air distribution switch; burned out fan motor; inoperative vacuum solenoid motors controlling air distribution flaps.

But check the vacuum accumulator first, if under the spare wheel, the lines are easily dislodged.
