Chrysler Repair: Power Locks not energized, body control module bcm, chrysler voyager


Question
QUESTION: The power locks will not function by the key transmitter nor the lock button on the door. Side doors respond as well as the lift gate in the rear.  I would believe that a fuse is out but can not find anything in the owners manual.
Can you make a suggestion.
Thank you for your response.
