None of the chimes in my 99 Jeep Grand Cherokee Laredo work. No key chime, no door open chime, no lights on chime, no seat belt disconnected chime. Where is the Chime Module and what does it look like? What would cause all of the chimes to no work other than that? I just bought this car and they have never worked since I got it.

Make sure you have nothing laying on a passenger seat since these are also equipped with sensors.
If these are free, try checking under your seat for wiring that has been damaged or become disconnected.

This sounds like normal operation to me. What's the issue?

Could be a faulty airbag sensor. Uses the same chime.

have it checed out by a air bag technitcian open squib means no contact in a squib need to be fixed

i think your switch in the door has just decided to pack up at the same time as you were working on the vehicle and its just coincidence or murphys law as we call it in the trade

what is the chime for? door ajar? seat belt not buckled? if you solve the problem the chime will go away

This chime is also the same chime used for the doors. To remove this you will also be losing the ignition chime when the keys are in the ignition or when the doors open.
It can be removed simply by unplugging it. Just open the door with the keys in the ignition, look under the dash on the driver or passenger side. using you good hearing locate the chime and simply disconnect the plug from the back.

I have a 2002 jeep grand cherokee Limited and Had similar problem. Found out that a wire/connection harness had gotten cut under PASSENGER seat.from seats moving back and forth. It's part of the airbag system, it tells airbag system if seatbelt is fastened and if occupant is in seat. Since the wire is broken, it can't report back to air back system and activates the light. try this, hope it helps.

Was the battery disconnected at anytime? You may try locking the vehicle up, putting the key in the tailgate to reset the security system.

Hi
There is a switch in the seat belt latch whe your sitting in the seat this will ba the part o the right side, see if something went into the latch part? or the switch is bad i think you have to replace the belt to fix the switch
