My daughter has a 2003 CCSB D/A that is loaded. It constantly has a message on the DIC RR Door ajar. Today I removed the lock assembly and checked the operation of the switch. It appears to work, but I am not sure of what pin does what. Unplugging the wiring harness had no effect on the door ajar message. Could this be BCM related? The remote start won't work either. There also seems to be an issue with the driver's side seat adjuster not working proper and the gear shift indicator goes dim after being on for a while. Any thoughts?
