My hearing isn't what it used to be, but I noticed that sometimes I wouldn't hear the chirp. I also noticed that one of the lock actuators was operating after the others.

I was having an intermittent brake light failure, so I cleaned the grounds in the right rear side. Then I checked the wiring harness that goes through the rubber tube into the trunk. I found a wire on which the insulation was broken. This was the red/black wire that supplies power to the trunk lock through fuse 53. I wrapped some tape around the wire and the whole harness.

I don't know if it was wrapping the wire or cleaning the grounds or something else or just luck, but since then the locking and the chirp and actuators work like normal.
