Don't do it. But if you want still to do that the speaker is located just next to the ignition cylinder. You have to remove the panel under the steering wheel if you want to modify factory options.
To turn off the seatbelt warning light on a Citroën C1, you typically need to buckle the seatbelt. If you want to disable the warning sound, you can do so by following the vehicle's manual instructions, usually involving a specific sequence of actions with the ignition and seatbelt. However, keep in mind that disabling safety features is not recommended for safety reasons. Always ensure that all passengers are buckled in for safe driving.
Why do you want to do that? You probably don't use the belts,right? Silence the seat belt warning by putting the belt on idiot. No you are the idiot. I am looking for the same thing because I have a dog and every time he gets off and back on the seat the bell starts up again.
Unplug the door switch.
Find and remove or disconnect the chime relay.
You can do this by locating the dinger under the dash and unplugging it. Once you have this unplugged, it will not make the sound anymore.
put the seat belt on
Lift hood, remove annoying horn by twisting, or jerking erratically.....voila!! No more beeps!
There's a wire under the driver's seat (under the carpet) that goes to the seatbelt, unplugging this will disable the annoying buzzer you have till u put on your seatbelt. An off note on that... The paramedics will also appreciate the lack of noise when they investigate how you died in the accident by not wearing a seatbelt...
I'm having a similar problem. The passengar seat belt will not close, which causes the beeping to never end. Currently, I have disabled the beeping. I removed the door panel on the side with the problem, unplugged the grey connector and placed a wire in the plug shorting it out to fool it into thinking the door is still open. Kevin
Annoying.
Simply cut out the speaker above the pedals If you look above you, where the rear view mirror is attached to the ceiling of the vehicle is the seatbelt light indicator. Carefully remove the cover and unscrew all five screws. You'll see the tiny speaker connection inside and simply plug it out.
Turns out it's Weather.com's desktop weather application notifying you of a weather alert/warning/watch. You can disable the sound in the program itself. It's been confusing me for the past 4 days til I just figured it out.
