Seatbelt warning light keeps flasing when seatbelt is fasten

What make , model an year vehicle ? Most vehicles will chime for a number of reasons , just depends on year , make ,model etc.....

The airbag light is on because there is something wrong with the seatbelt system each seatbelt has a electric connection and a sensor built in

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.

How many does it make after 10 minutes? Try fastening the seatbelt, or making sure the seatbelt sensor works. Its in the buckle down below the seat. If its unplugged, the seatbelt sensor cannot report that the seatbelt is fastened.

This is the seatbelt indicator, its not seeing that your seatbelt is fastened ifthe light stays on and the chime keeps going off.

There is a switch inthe seatbelt that closes when the seatbelt is buckled, and if not, thelight stays on and the chime goes off.

There are a couple reasons thiscould happen. It could be a wiring issue going to the seatbelt buckle,or more likely the buckle itself. Your truck is pretty new, so if youare under 36,000 miles the repair would normally be covered underwarranty.

Also, I suggest check the Repair Manual for Jeep-WK-Grand-Cherokee-Section-08O-Restraints (page 473 and next, for Seat Belt)

Hope helps with this (remember rated this) Good luck.

sensor in the seat belt bukle needs to be replaced

You mean when the belts are not fastened right?
In the owner's manual it talks about how to disable the seatbelt warning by fastening then unfastening the belt in an exact pattern at an extact time.
I do not know if that will help but it may be a key to finding a solution.

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

you need to be sitting in the drivers seat, not the passenger.

your doorswitch is inside the door on the striker latch. You will need to remove the door panel to access. chances are it is stuck in the closed position. Your seatbelt latch sensor has also gone bad. It is located inside the receptacle of the seatbelt. If you only want to diengage the light, look for the molex plug attached to the wire coming from the seatbelt receptacle.
