OK the driver door puddle light, code access buttons, and power door lock button do not work while engine is off. BUT... the door lock button works when engine is running. Also, It seems as if the car doesnt know the door is shut (door ajar sensor) because when i hit the lock on the remote it beeps twice (like a door is open) and another thing is that the dome lights stay on for far too long (like the door is open) I have checked most of the fuses but cannot check the relays (silver can types) Can anyone diagnose what is blown that powers this door after the engine is off?

they all have the same power feeds whether key on or off. the body control module controls these functions. you need a shp with a scan tool that can monitor the operations of these items and determine if the bcm is bad or needs to be flashed. Roy
