If there is weight on the seat, it senses that (probably a spring systme), and if the seat belt isn't in the buckle (there's a sensor there as well), the light flashes or it beeps.
There is a sensor in the buckle.
Seat belt cilker.
i have a 02 trailblazer and that happened to me. was the air bag sensor, yes.i think the dealer charged me around 220.00 to replace the sensor.
Because they dont have sensor in seat
Which "sensor" are you asking about? I have many in my truck beginning with the seat-belt sensor that says if I have buckled-up or not.
It is probably because the sensor under the seat for the seat belt has disconnected --Same thing happened to me. The light would go out when I pulled on the seatbelt. The reason was the simple fact that the belt was twisted before it came out of the shoulder "bracket". Oh... The sensor is in the door post, not under the seat. I also thought of that eventuality and checked. Nope, no sensor under the seat!
Is this a safety issue
unplug the sensor attachment from right under the seat
If you examine the buckle that you snap your seatbelt latch into, you will notice it has wires attached. That is where the sensor is.
the receiver for the belt has a sensor. if it fails the light will continue to flash even though the belt is buckled. replace it!
Under the seat there is a wire that runs to the seat belt lock. It has a conector which you can unhook. With this disconnected, the bell will not sound while you are in seat without the seatbelt buckled.
Yes it will! There is a sensor under the seat (passenger side) that senses the weight of a person in the seat. The Air-bag systems also have a sensor in them that detects sudden impact in specific directions. However - air-bags are designed to be used in conjunction WITH a seat-belt. The idea is - under rapid deceleration, the seat belt locks and the air-bag simultaneously deploys.
