GMC Repair: dome light and dash indicator all 4 doors open, chevy malibu, body control module

Question
2001 Chevy Malibu v6 3100 engine   Why does dash indicator
show all four doors open and dome light will not turn on/off with doors

Answer
Hi
I would suspect possibaly the BCM (Body Control Module).
BEFORE you replace this expensive part, I would have it checked.
Any shop should be able to communicate with it,check for codes first. Then see if the data for the door ajar switches are closed or open with same door closed or open.
If it all matches, they should check for any wiring issues.
If all checks out the BCM MAY be the cause.
I hope this helps
