Works the same as the rest.......since there is no 'Door Open' (ajar) warning, along with no 'Key in Ignition' chime as well as no interior lamp it will be a latch or wire harness failure.

I haven't heard of any wire harnesses breaking (yet) but have heard of many latch failures.

Currently,my money is on a bum latch.

The problem with this is the new latch has to be programmed for the BCM to recognize it.......obviously a dealer will be involved at some point.

The new part has to be 'introduced' to the BCM in so many words.

The replacement part currently can't be identified because the BCM does not recognize the parts new broadcast code.
A 'Lost Communication' code results.....the BCM does not recognize the new code coming through the system.....it is looking for the previous code that was assigned to the old part.

For whatever it is worth, the level of complexity is more aggravating by the day.......all in the name of reducing the amount of secondary switches and wiring.....ugh.
