DTC Code Help

I have some fault codes that I would like some help diagnosing. None of them affect drivability (that I am aware of) but it would be nice to take car of any issues preventatively.

CEM_H (Central Electronic Module): 1 DTC
--> CEM-6A01: Rear left door unlocked. Signal too high.
CEM_L (Central Electronic Module): 1 DTC
--> CEM-6A01: Rear left door unlocked. Signal too high.
-The door lock operates normally. Is this a sign that the door lock motor is on its way out?

DDM (Driver Door Module): 2 DTCs
--> DDM-0025: Door mirror motor. Disconnected.
-The mirror adjusts normally but I have noticed that the heated function of the mirror has stopped working. This may be a moot point as I have a set of 04 mirrors that I am going to be installing as soon as I get the covers paint matched.
--> DDM-002B: <unknown DTC>

Any help would be much appreciated!

Don't worry about it
These are always there on all these cars.
One time it got a faulty signal for whatever reason and a code is set.
Clear them all out and don't worry about it until the lock fails (IF it ever does)!

That's what I was thinking. I have cleared these codes multiple times over the past 3 years and the codes always immediately come back. Might be a good idea to pick up a used door lock actuator at the pick-a-part next time I'm there so I'm prepared if/when mine fails.
