My passenger door has no power,my security light is on constantly

Try using the door key to lock and un lock the drivers door. Pulling the fuse for the security system will guarantee the engine will never start.

The problem is caused by either a defective door ajar switch or the interior light relay. it can be any of the four switches, so the best thing to do is have the BCM scanned to see which switch is the issue. The switch is attached to the door latch inside the door.

It might be the door ajar timer box or check door ajar switches first

hi -door ajar switch is built into the door latch inside the door. The latch latches to the B pillar. It may be this switch or a wiring problem, or a bad drivers door module (DDM). Remove the inside door trim and check the wiring and connectors. The wires from the door switch are tan and gray/black and run to the 8 pin connector of the drivers door module. By peeling back the plastic shield, you can get to the wires for the door ajar switch at the latch. Disconnect the 4 pin connector at the latch. Test the radio now to see if it shuts off. If it does, the door ajar switch is bad.

What was done at the dealership that lead them to believe that they fixed it?

Replace the door ajar switch.

You need to replace the door jamb switch. Little button on the door jamb that is pressed in when doors are shut.

Probably inside your car underneath of dashboard or on the passenger side when you open the door on side of dashboard.

take and spray wd40 on the latches and open close the door a few times and that should fix the problem that is what was wrong with mine. That took care of problem if that doesnt fix it the senors need to be replaced in the latch

not sure what to say but check recall on your vehicle might be a wide problem...could get fixed for free
