Cargo door adjar warning

[chainsaw4130]

In the Message Center of my Yukon the "Cargo Door Ajar" message will flash when I haven't open the cargo door for days. Does anybody know where the sensor is? I would like to take a look at it before I call the dealer.

You might want to check the electrical contacts at the top of the doors.  They get dirty (or wet) and don't make proper contact.  That's been the case with mine.

The micro switches are on the latches.  I had that trouble with mine.  I found that if you don't really close the door agressively one of the latches may not completely lock over center and at some later time may trip the switch, thus turning on the door ajar light.
