Having problems with your 2003 Cadillac Escalade Ext ?
Left rear door ajar has been on for a while and i was told its the bcm. wondering if it might be something else?
Yes it is not the BCM in my opinion it is the door ajar switch inside the door that is defective, a common problem. Have a GM dealer run a BCM self test to confirm this.
