OK for the rear it is still a bad ground and black wire. The ground location is different though and the rear light has three black wires that go to the ground 924A location. Still the same issue though. What they do is take 2-8 wires and crimp them all into one eyelet. Get a bit of corrosion in there and you get lights or other items that just stop working, but the crimped area looks perfect and as a result it's treated as good, and you get charged for bulbs, then a complete lamp assembly, then a BCM and finally you get fed up and bring it to someone who knows these vehicles who says, "Yep, you're describing a bad ground" and 20 minutes and a 6 pack later you have working lights again. In your case, access the light harness and find the three black wires that all go to the same ground in that brilliant design. This is how you can tell that vehicle has European engineering, It was a joint design of Daimler and Mitsubishi and it is overengineered in a bad way. The easiest repair is to take all three wires there, cut them at a convenient length, then either crimp those to a new wire that you attach to a handy ground point with a screw or find the other end under the panels, cut the wires there and add new ring terminals and ground them there.
