Driver side seat-belt sensor continuously triggers warning

[Alex05]

I'm out of 5-minute fixes to try and solve this, without getting janky.
The issue is:
The driver side seat-belt sensor is likely faulty. This manifests itself by constantly flickering the seat-belt dash warning light. I've likely determined that the dash light warning itself is not the issue, because with the warning light off solidly, I can unbuckle and the warning light consistently stays on.

What I've tried:
Checking for loose connectors. I located the two-wire connector under the seat, disconnected it, sprayed both the male and female end with contact cleaner.
Blew compressed air into the seat-belt receiver

This isn't much of an effort, but I'm also not sure what else to try, short of just replacing the seat-belt receiver. Which costs ~$100. Ultimately it's a simple piece of equipment, IMO, specifically the seat-belt receiver.

I'm trying to avoid bypassing the sensor, or just putting a piece of tape over the warning light. Though I'll admit, the tape is looking pretty tempting, especially while I'm driving at night.

Thought it better to revive a dead thread than start another one - I'm having a similar fault with my driver side belt receiver. It doesn't turn the seat belt warning light off unless i jam the buckle down into it - almost as if the buckle isn't long enough to keep the switch inside down. Has anyone come across this before? i figure if I can get an easy fix, I'll replace the buckle with something from another car, items for TJs are expensive to get hold of here

i just unplugged mine. Connector is under the seat.

Does this leave the light constantly on or off? I'll still need to repair it for inspection but it would do for now!

My light is off.

Unplug that seat's seatbelt sensor connector, you'll never hear the seatbelt buzzer/light/chime again.

I am in the habit of wearing my seatbelts and don't need a damned buzzer/chime to remind me. Especially when I'm just moving the Jeep to a different position.

I even removed the device (called a sonalert) from the back of the instrument cluster since I have a real thing against buzzers and chimes telling me to do something.

Does anyone know if the seatbelt sensor reading buckled/unbuckled affects how the airbags would deploy?
FWIW, my issue got better by pushing the crimped metal around the wire inside the connector further into the connector.
Not sure that totally makes sense, let me know if you'd like to see a picture.

The airbags are on a completely different circuit, they'll go off no matter what you do to your seat belt wiring.

 

[Alex05]

Jerry, often times whether or not an occupant is buckled affects airbag deployment timing. Though, this would be pretty next level engineering knowledge in terms of how the airbag sensors operate.
Ultimately I would rather figure out a way to fix a minor issue that could potentially cause a much larger issue, than go out of my way to work around the issue

 

[Jerry Bransford]

The only thing that affects the TJ's airbag deployment is the airbag's deceleration sensor located underneath the console at the very front. That sole airbag sensor present in a TJ couldn't care less if the seats are occupied or if the occupants are wearing their seat belts.

Reviving this thread again

What if the the sensor is already disconnected under the seat and still randomly get the chime and light while buckled.

This just started this week and I've had this gal for 3 months now.
Would LED turn signals that aren't grounded maybe have something to do with it? I also cant get my amp to work on this jeep, it will work for 30 seconds then go into protect mode, so I'm starting to think all of these electronic issues could be tied back to the stupid LEDs the PO put in?
Only thing I've done to fix the turn signals so far is the LM470 relay, which did take away the Hyperflash, but both turn signals stay lit when I have my lights on and my front signals flash white instead of yellow.

 

[TripMcneely]

The PO also mentioned when I picked it up that you didnt have to use the clutch to start it, but didnt mention how he had achieved that, so about a month later it starts acting funny for a couple days having to press the clutch sometimes to start and others not till it eventually wouldnt start at all one day clutch or not, Googled around and found if you put a 10V fuse in the 20 hole it would bypass the clutch, which worked, but that post also mentioned that it made hios 4x4 light stay lit and other odd things so maybe that has something to do with this seatbelt light and chime as well, idk.
Electronics are not my strong suit.

I have a question regarding this seat belt warning light issue, please. I'm glad this thread was revived. Mine is a 1997 Wrangler TJ Sport. I am the Original Owner. At some point, my selt belt warning light stopped working with no light. When I turn the ignition both the seat belt and Air Bag lights come on, then when I start the Jeep, they both go off. I remember that the seat belt light would stay on until the seat belts were engaged when I first brought it. I want to fix it. My question is, 1. Are there sensors under the seats on both front seats, and then electronics attached to both seat belts? At some pooint I believe that things were removed, or disconnected, and I want to restore all working parts on my Jeep. Thank you.

 

[TripMcneely]

I only have the wires under the drivers side.

 

[ChasUGC]

Yeah, I just checked. There only seems to be hardware on the driver's side. Now, I have to find out why it doesn't work anymore. I have no lights except for the ignition turn and then it goes out.
