My problem w/ my 2006 Escalade is not the typical secondary latch catching when the tire goes down 3-4". I have a similar but worse problem. The cable lowers but the spare is jammed up tight and will not budge. The tire cannot even be rotated it is so tight. Also, the mechanism on mine does not look like the ones on all the videos. I just got new tires and the guys at that shop had no idea how to release it.
