Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
The passenger, and both rear doors do not lock with the door button or the key remote. is there a quick fix?
(1) Answer
I cannot say for sure on a 97 but on a 98 Century the lock and unlock relays for the passenger and rear doors are inside the Body Control Module. If the doors unlock but do not not lock then I would suspect the fault is with the BCM. Before replacing any parts please confirm the at the systems are the same for a 97 and 98 Century and perform the necessary diagnostics to confirm the fault.
