BMW 320d e46 2001 vent direction control not working

When you move vent direction control on heater control panel and use blower air is vented from windscreen vents irrespective of where control knob is set. Check shows that solenoid is moving control in heater but always returns to windscreen. Can solenoid control be accessed from engine compartment or does whole dash have to be removed to check.
I have replaced heater control panel but still have same problem

SOURCE: 2001 BMW 330i..Fan for AC/vent not working?

I just replaced the "Final Stage Resistor" in my 2001 330i. Fixed the probelm 100% !!!. I followed the instructions descibed found here and on other sites. A little challenging, mostly becasue I hate working upside down, but the repair went as descibed. If you're even moderatley handy this is a straighforward project. I'd say about 60 minutes to carefully remove everything and about 30 minutes to put it all back together. Beats $500+ at the dealer!

it's either a fuse or it's a bad blower motor, it could be a bad blower motor resistor but usually you'll get either high or low only, so if you have nothing on any speed, high low etc, and all the fuses are ok chances are it's your blower motor.

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

all cars have a recycled air weather its called max or just recycle its doing the same thing. So if your getting cold air in one spot and hot in another it means your vents are not blocking where they are suposed to. It could be just a simple fix, by getting into the dash where your vent controls are and looking at the flap that tells air where it can and cant go. if its stuck then it needs to be cleaned and oiled. If the cable is corrodend clean it and oil it so it can move freely, or just reconnecting it may be the fix. it sounds like you are going to have to be adventurous, and play with the mechanics of your vents. Typicaly theres really nothing tough there to work on, just REMEMBER WHEERE ALL THE SCROOS AND CLIPS GO. I have forgotten where a few went in the past and had to listen to sqeaking noises till I took it apart again. There are vent seals wich are no more than the weather stripping you buy at the hardware store the 1/8 inch thick tape. You may need to thin it down with a razor, usually not. but it works great for fixing the seals in car heaters, because its the same thng just a different color. Which no one will ever see.

Why would my blower, vent, defrost, ac and heater just quit blowing air?

There are several possible reasons why your blower, vent, defrost, AC, and heater might stop blowing air:

1. Blower Motor Failure: The blower motor is responsible for blowing the air through the vents. If the blower motor fails, you will not get any airflow from the vents.
2. Blower Motor Resistor Failure: The blower motor resistor controls the speed of the blower motor. If the resistor fails, the blower motor may stop working or only work at one speed.
3. Fuse or Relay Failure: A blown fuse or faulty relay in the blower motor circuit can prevent the blower motor from working.
4. Control Module Failure: The HVAC (heating, ventilation, and air conditioning) control module is responsible for controlling the blower motor and other components. If the control module fails, it can prevent the blower motor from working.
5. Vacuum Leak: If your vehicle uses a vacuum system to control the vents, a vacuum leak can prevent the system from working properly.
6. Broken Blend Door: The blend door controls the direction of the airflow. If the blend door breaks or gets stuck, the air may not flow through the correct vents.
7. Wiring or Connector Issues: Faulty wiring or connectors in the blower motor circuit can prevent the blower motor from working.

Hi All, I have a W-reg (year 2000) 318i BMW and my air blowers are playing up. The temperature is fine, the blower speed is fine but the directional controls need repair. The screen and footwell blowers...

Most likely you have electrical control. Since you have defrost and footwell heat. So you have to replace the motor that controls the vent door. You can find the location online, as I don't have them.

How to repair

i'd think that the vent adjuster knob/slider is not working correctly strip out the heater panel around the control knobs and check the vent direction is working properly either stiff operation so a little wd40 on the cable would probably do the trick or some thing causing the vent itself to not move

Heater not blowing hot air

IT could be one of several things: possible the blower fan motor is bad; or the valve that lets the hot water in from the engine to the heater core is not opening; or the door that lets the air flow past the heater core and onward to your vents is not opening. All these are controlled by your heater switch, via relays and vacuum lines. If the blower motor works well when you put power to it directly, but not when it is hooked to the car, a connection in the switch or a relay may be bad. if you get little or no effort from the blower motor when you hook it directly to a good battery, it's the blower motor itself gone bad. If you get airflow but not heat, it's the device which diverts the hot water into the heater core. and if its the door to let air flow over the heater core, it could be a relay, a vacuum hose or the switch.

1990 Dodge Caravan A/C / Heater blower fan mode control won't work

The mode doors are operated by vacuum. Check the vacuum supply line to verify it is connected to the intake manifold. If that looks good, remove the control panel to see if vacuum is coming to the mode switch. Then check to see if the switch is transferring vacuum to the actuator lines. Here is the panel removal procedure:
  1. Disconnect the negative battery cable.
  2. Remove the necessary bezel(s) in order to gain access to the control head.
  3. Remove the screws that fasten the control head to the instrument panel.
  4. Pull the unit out to troubleshoot.

My air conditioner is not working on my 2002 BMW X-5. The air is cool it just won't blow out.

If there is air moving through the vents most likely the final stage transistor(blower resistor) has failed. It controls blower speed from a signal from the ihka (a/c control panel). the final stage receives the signal from the ihka of the drivers preference blower speed. the final stage pwm (pulse width modulates) the blower motor. which means it turns it off and on very quickly to speed up or slow down the blower motor speed. It isn't the easiest part to replace. Usually at a dealership i would expect to pay somewhere around $600 (including diagnosis)but don't hold me to it. bmw dealerships stand behind their repairs and usually include a warranty with the part of 2 years unlimited mileage.

Blower vents on 86 regal

The blend door in the heater box itself is what directs the air to where it needs to go as per selector switch. The heater box is located under the dash.
