Have a 2007 Exp. EB. from time to time the liftgate opens on its own unless the doors are locked. It doesn't matter if the engine is running or the ignition is on. So far it hasn't opened while vehicle is moving. Its not the key fob because I don't use it. I have been miles away from the fob and it happens. All fuses good. Have reset it. Any suggestions ?

 

I would start by disconnecting the switches. If the problem goes away you know it's one of the switches. If not, you can move on to the wiring and relay.
