I just purchased a 2018 durango GT blacktop edition. My front passenger door handle light flickers, goes out, or sometimes works correctly. I've done the "bang on it" procedure to see if vibration causes any change. No change. I've wiggled the wiring harness that goes from the door to the car... no change. Before I start digging into it, has anyone had this issue? Is the part replaceable? Any help with repair tips or where I can get a replacement part would be amazing. Thanks!
