Re: heater blower not working
It sounds like your cabin air filter has stopped up common problem on these cars. You have to remove the glovebox to get to it. If this filter stops up, your fan will be running on high but hardly anything will come out of the vents.

possibly a problem with the button on the end of the stalk.
sounds like your indicator stalk needs changed out.
I had a similar problem with the other side and my intermittent wipers. changed the stalk and it was all good.
are you talking about the fan blower inside the car or the fans under the bonnet..?
the fans under the bonnet may stay on for a while after the engine is switched off to prevent heatsoak. This is when the engine actually heats up more after switch off due to latent heat within the engine. The fans will remain on until the coolant temperature has fallen and stabilised, then the fans will stop. If the blower fan inside the car keeps running, this may be a feature on the car to assist with heat soak but I would think this is more like a faulty power relay or fan controller if the car has climate control..In this case, my advice would be to consult a qualified autoelectrician.
Hello picotto2006....Your beemer blower motor has a resistor that controls and regulates the voltage and speed. This has been known to to fail due to intensive heat. A lot of beemer owners have replaced the orginal factory resistor with an aftermarket upgrade. It is a rectangular plastic or fiberboard unit and should be bolted to the base of the heater box. This resistor has most likely failed. Replacement cost is about 75 dollars for the E46. Attached is a picture of the resistor. Good luck and i hope this will fixya up and get the beemer heater back in operating condition.
it is most likely the window switch, motor, or most likely the lifter assemby. The lifters are a known issue with the windows. If you have a meter you can check the power delivery to the motor contacts (rear door panel removal required). If you don't have a meter then you can try to listen for the motor to engage when you press the button. To check the button, you again need a meter to check continuity. Remove the centre concole, disconnect wiring harness from button, and depress. With a meter attached you can tell if it's making contact. Often, because of the locatin of the bottoms, they can get dirty or damaged and require replacement. Once you've isolated the faulty component, a good source for the replacement parts is Pelican. http://www.pelicanparts.com/bmw/catalog/shopcart/BE46/POR_BE46_ELswch_pg5.htm
