91 toyota camry door ajar light stays on along with the chime

There isn't a chime module , built into instrument cluster !
Door Ajar Chime
The door ajar chime feature is controlled by the smart junction box (SJB). The driver and passenger door ajar switches, and the lift gate are hardwired to the SJB. If any door or lift gate is sensed as being open, and the ignition switch is in RUN/START position, the SJB will process the input and sends a chime request to the instrument cluster over the controller area network (CAN).
Safety Belt Warning Chime
The safety belt chime feature is controlled by the restraints control module (RCM). The driver safety belt switch is hardwired to the RCM. The RCM communicates with the instrument cluster over a hardwire connection. If at any time during the first 6 seconds after the ignition switch is placed in RUN the driver safety belt is sensed as being unfastened, the RCM will process the input, and in turn, sends a chime request to the instrument cluster.
Do you know what C.A.N controller area network is ? Serial data communication bus.

somehow I was the annoynmess person with the question about the door ajar and a seatbelt alarm that we disabled, and odometer quitting the radio stayed on well it was just a plug and the odometer speedometer all that works now, but the radio still stay on with a key out of ignition, and now the AC don't cool

There is another legitimate and easy way to disable seat belt chime. Radio is supposed to stay on til door opens. That is correct

hi Ron.
see if this link helps you out.
Location of fuse for dash lights on 1996 Toyota Camry Google Search

Could be the sensor in the key switch telling you the key is still in the lock.

Get in the car, make sure your dome light is set to door-operation.
Close all the doors, does the dome light go out?
If so, it's not the door ajar chime. If not, one of your door pin switches is defective.
Buckle your seatbelt, does the seatbelt warning light on the dash go out?
If so, it's not the seatbelt alarm. If not, it's the seatbelt buckle receiver.
The light warning works with the key off, so it is not that since turning the car off would not stop it.
Last thing it could be is the ignition key alarm.
I have seen a few malfunction over the years.

If there is anything, that is in any way "burnt", it needs to be replaced.
I would try a local auto recycler before I ordered a new light failure sensor.

try a higher amp fuse

2 possible problems one might be the ignition switch is not powering up those components,the other might be the gem module its like a body control module and it runs those components

there could be chaffed wires that r grounding
