The seat belt light comes on, even if the seat belt is fastened. I've discovered that the sensor/switch on the buckle is intermittent. I would like to know...is this used for anything other then the light? Not used for any of the supplementary restraint mechanisms?

In seat belt there's a sensor that tells when seat belt is buckled. The sensor isn't registering that belt is buckled. Have belt system checked out by dealership should be still under warranty. Don't think it's connected to battery problem

You can disconnect it yourself. There is a wire lead that comes from the seatbelt fastener, you may need to lift the carpet up a bit. This lead will have a connector, dis connect it at the connector. This will deactivate the alam, however your seatbelt light will remain on. From here you can see where the malfunctioning switch is, if you feel confident to change it.

Maybe a bad switch or something in the belt latch,
I unplugged mine at the floor where the right belt anchors,
Now it's quiet,I still know if the belt is on or not by the way it feels !!

Check under both seats and make sure the wire harness is plugged in all the way. Some times shoving stuff under the seat unplugs wiring harness; seat belt sensor, occupant weight senor for air bags, heated seats & power seats (could be more than one wiring harness. Look inside belt buckle fastener; is it crusty with anything (food, crumbs, coin change)? Blow it out with a portable can of air. Make sure both the male/female parts of belt are clean, non-rusted/corroded & non-damaged to make good electrical connection when belted in; this turns off your belt warning light and bell. Check all wiring from the belt buckle release a the way down to under the seat; both sides...both seats They both seats could be interlinked into system; when one fails (bad connection) the other seat sensor fails also.

Try looking for a wire that connects to the seat belt somewhere under the seat it could have become disconnected or cut. Also try taping the fastener with something like a hammer maybe a bit of WD-40 cause something might be sticking inside the fastener.

We both know that that's a reminder light to fasten your seat belt, the switch at the seat belt buckle is not making connect, check connection or possible bad switch.

there is a switch in the buckle that tells the system u have the seat belt on, it may be defective.

If the seat belt light comes on intermittently with the belt buckled, it may have a bad switch in the buckle or a loose connection @ the switch. This may also set a diagnostic trouble code in the srs control module & keep the srs airbag light on.

Soak it soak it and soak it....... may take a few days.... If nothing works, get a hair dryer and heat it up warm to the touch..... melt wax all over the quite warm bolt unit and let sit overnight.... as it cools it will draw the wax down along the threads
