Welcome aboard buddy, what year model you got? You can try this, from p. 58 of 2001 OM 6th edition:
"BeltAlert�� can be enabled or disabled by your authorized dealer or by following these steps:
NOTE: The following steps must occur within the first 60 seconds of the ignition switch being turned to the ON/RUN or START position. Chrysler Group LLC does not recommend deactivating BeltAlert��.
1. With all doors closed, turn the ignition switch to the LOCK position and buckle the driver or front passenger seat belt.
2. Turn the ignition switch to the ON/RUN position and wait for the Seat Belt Reminder Light to turn off.
3. Within 60 seconds of turning the ignition switch to the ON/RUN position, unbuckle and then re-buckle the driver or front passenger seat belt at least three times within 10 seconds, ending with the seat belt buckled.
NOTE: Watch for the Seat Belt Reminder Light to turn on while unbuckling and off while re-buckling the seat belt. It may be necessary to retract the seat belt.
4. Turn the ignition switch to the LOCK position. A single chime will sound to signify that you have success- fully completed the programming.
BeltAlert�� can be reactivated by repeating this procedure.
NOTE: Although BeltAlert�� has been deactivated, the Seat Belt Reminder Light will continue to illuminate while the driver or front passenger seat belt remains unbuckled."
