Customer Question

2006 cadillac escalade esv platnum the key fob only works for the front drivers door and the front passengers door it dosen't work for the hatch or the two back doors. Is there a hidden button or something that I missed that could automatically open them without opening and locking them manually?

Looking at the schematic, it seems likely that there is a problem with a ground connection, as that's the one thing that all three devices have in common. It's called G203, and it's fairly hard to access.

Do you have a test light or a meter that can be used for testing circuits, or is this beyond your capability?
