2008 vw rabbit seat belt light stays on even when fastened, is there a fuse I checked under seats everything seems to be plugged in

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

Sounds like the weight sensor in the passenger seat may be defective.

Could be a problem with the sensor in the seat. The system thinks someone is sitting in the seat and the seat belt is not fastened.

fastening seat belts is not always the answer as some sensors need weight to cancel the light after the seatbelt is fastened. best have it checked out by an auto electrician as the seats may have been changed and the wiring not properly connected.

Probably no need to see an expensive mechanic. My seat belt warning light came on a few days ago when there were four people in the car and the rear seat belts weren't fastened (I thought that was why it lit up). However, the light came on and stayed on when I was the only person in the car. Logically, it suggested a bad connection somewhere, so I checked the connector under the passenger seat and made sure it was properly fastened together. I then sprayed a small amount of WD40 into the female clasps of both front seat belt connectors, clipped and unclipped the belts a few times and the light is now fine. Try it - it worked for my 2003 Escape.

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.

Usually a sensor in the seat that recognizes a body in it. Check under the seat for any plug that may have disconnected. maybe someone kicked it with their foot.

you have elements underneath the seat cover most likely the drivers bottom seat element is burned out, you can check the resistance of it with a on ohm meter there is a 2 wire connector that goes to the backrest and then a 2 wire connector that goes to the seat cushion, more likely its the seat bottom that is burnt out

you may have 2 problems 1 ightion switch and a seat belt pretensioner both faly common problems

More likely to be a sensor - check gsf (google it - german, sweedish, french car parts) for the seat belt sensor
