If you had the ignition on while the air bag was disconected the warning light will stay on until reset by a computer, I disconected the 2 sensors under the front passenger seat on my 318i ES when I removed the seat to dry water from the footwell area I had the CD on so the ignition was on, one of the sensors is to do with the air bag, this is called I think an inflight warning light it will not reset I disconected /reconected it several times to no avail, it's only expensive to reset if you let BMW take the ****, ask around you will find a garage that has the leads plugs ect .

Does the air bag need to be disconnected when replacing a stearing wheel cruis control switch on a 2001 buick lesabre custom?


Anytime you are working on the steering wheel or steering column, the battery should be disconnected and the power drained from the car.
If a wire is shorted in the air bag circuit the bag could deploy.
Even if the ignition is turned off.
The standard procedure is to leave the door open and disconnect the battery, then wait 5 or 10 min to drain power from the car.

Window does not lift drivers door


The window regulators in e46s are notorious for failure.
Often, you can fix them with zip ties. Failing that, replacing the regulator is not too hard.
Disconnect the battery before starting to remove the door panel because there is an air bag in the door panel.
Pry up the trim strip starting from the rear. Remove all the screws that hold on the door panel. One of them is hiding beneath the mirror control button. Pry the switch up out of the door to find the screw.
DO NOT connect the battery and turn on the key while the air bag is unplugged.
Once you can see the regulator, you may be able to see where the cable has broken loose from the regulator. You may be able to zip tie it back in place. I did that several years ago on my wife's '04 330 and it is still working.
You can get a window regulator for this car on Amazon.com for $50 or you can get a BMW regulator for $150. Since we know that the BMW part is crappy, the $50 aftermarket part from Amazon might be worth a try.

Window on driver side is off track..how do i fix it..is there an air bag that will deploy if i take panel off


There is an air bag in the door and it can hurt you.
Disconnect the battery for a while (no one seems to know how long, but several minutes at least) before disconnecting the air bag.
Don't connect the battery and turn on the key to check your repair while the air bag is unplugged or it will set an error code and you will have to take it to a shop to have the SRS system reset so the SRS light will go out.
I expect that the problem is not that the window is not off the track, but rather that the regulator is broken.
I am not familiar with the 5 series, but the window regulator picture in the parts book looks similar but not quite the same as the one used in the 3-series. In the 3 series, the regulator is not difficult to replace, but it is much easier and cheaper to fix the broken one with a couple of zip ties. I fixed the driver side window regulator in my wife's '04 330 with zip ties years ago and it still works fine. I would pull off the door panel and look at it to see if it is fixable in place before ordering a new regulator ($150 on line)

My window on my bmw goes down a qauter ways and it gets stuck and dosent go down all the way how do you fix it


Window regulators in early e46s are notorious for failing. If this is the first time it has failed, you must not use your windows much. Many of them had all four of their window regulators replaced before they got out of their original 4-year warranty.
Replacing it is not difficult, but repairing the broken plastic piece by wrapping a couple of zip ties around it is much easier and quicker and very cheap. The driver door in my wife's '04 330 has had zip ties in it for a couple of years and works just fine.
You will need a Torx head screwdriver set to remove the inner door panel. You pry up the trim strip starting at the rear to expose screws, and there are more screws beneath the mirror switch and below the big door handle. Be sure to disconnect the battery several minutes before removing the air bag, and handle the air bag carefully. It can hurt you. DO NOT connect the battery and test the repair while the air bag is disconnected or you will need to pay someone to reset the airbag (SRS) warning light.

How do I remove door interior to access the door lock mecanism ? on both door !


You will need a Torx head screwdriver.
First, disconnect the battery and leave it disconnected for several minutes because you don't want to lose a finger in the window mechanism or have the air bag blow up in your face.
Next, starting from the rear, carefully pry up the trim strip that runs from the door latch back to the back of the door. It is usually wood-grain finish, but may be aluminum or carbon fiber, depending on your interior package. Remove the screws beneath that trim.
Pop out the two oval plugs from the underside of the door handle, and remove the two screws beneath those plugs.
Now with something large and flat and preferably with no sharp edges, start snapping the inner door panel off. If you break some snaps, no worries. They are available on line for $0.35 each or at the dealer for about $1 each. The top of the door panel does not hook in the window sill like most cars, it snaps straight out.
Now disconnect the speaker wires, mirror control, and probably the air bag. You can leave the air bag connected if you are willing to work around it.
I presume that your window regulator is broken. Specifically, the piece of plastic that attaches the window mechanism to the cable. You can replace the whole regulator, but on my wife's '04 330i, I chose to put two good quality zip ties around it. One just above the broken piece and one just below it. There are holes and notches in the metal backing plate that work great to hold the zip ties in place. I did this repair a couple of years ago and the window still works just fine. Much quicker and cheaper than replacing the whole regulator.
If you unplug the air bag, DO NOT connect the battery and turn on the key to check your work while the air bag is unplugged. Doing so will set a critical fault in the SRS system that only a dealer or well-equipped BMW repair shop can clear. DAMHIK

How can i disable passanger air bag on 1999 z3


It's never a great idea to dis connect any safety feature on a vehicle. But should you wish to do so here are two possible options. BMW may have a key operated switch (usually ignition) to disarm the passanger side airbag (usually in the case of rear facing child seat being fitted) OR if you manually disconnect the airbag (NOT reccommended) you will have to insert a resistance into the passanger bag circuit of equivelant to the air bag that was removed.In order to maintain the self diagnosis check system.

Disconnect driver side air bag to work on power window


The side impact air bag in the door? Unhook the battery. Wait 5 minutes, then unbolt it and unplug it. It will be fine. Don't hook up the battery with the air bag unplugged to test the window, it will set a trouble code and the air bag light will be on until you go to the dealer and have it reset. Just make sure before you hook the battery back up the airbag is bolted back in place and plugged in.

Shouldn't set off air bag if you are taking off door panel. You could always disconnect negative battery cable to be extra careful. I have replaced both passenger and drivers windows with battery connected. Take your time in removing door panel so avoid breaking plastic retaining clips.

One nasty part of this job is removing bolts that hold window motor to the door. They have a rubberized nut on the backside. Sometimes you can hold them with vise grips. I've found if I just pull the motor really hard the bolt and nut slides out of rubber guide.

It is also a little tricky to remove the unit and reinstall it in the door. Just be patient and take your time.

One tip is to leave the door panel off after you install the new door motor/regulator unit. Simply plug in the window switch and make sure all is functioning correctly and then install door panel.


I buy the replacement window units online and save big bucks over the dealer.

2002 Boxster driver side window will not raise. Had a plastic cupholder hanging on side of window channel for years with no trouble. But that could ahve been the culprit today. Can hear the motor try. Then...


It sounds like you have a bad window regulator. This is the mechansm that the motor is bolted to that raises and lowers the window. Removing the door panel is difficult and is really a job for a porsche mechanic. Its easily damaged and there is the side air bag to deal with. You'll need to disconnect the battery and let the car sit for a couple of hours to discharge the side air bag capacitor before starting work, so you'll need the radio code to reactivate your radio. The panel is attached to the door with screws behind the door handle and inside the door pocket. It needs to be disassembled as it is removed. Behind it is a door air seal held in place by snap fasteners. Each of these has to be carefully pried out to remove the door seal and expose the window mechanism.
Its time-consuming and not something you want to do if you don't have replacement parts on hand.
After you have got it apart, you'll want to disconnect the air bag before you connect the battery up to test the window operation and see what is wrong. Don't forget to disconnect the battery again before reconnecting the side air bag.

Air Bag stay on BMW Z3 2003?


There must be a problem with the air bag system for the light to be on, if the system was o.k. the light would be off and have a stored code. You cannot reset this light with a generic obd2 scanner. You need to access the air bag system and read what codes it has stored. Good Luck.
