Hello everyone! I bought a 2007 R350 a couple months ago and its been a journey. So basically the rear hatch will not open, I mean the motor makes no noise. The rear latch releases and latches when you shut it so I don't believe that's the problem. I found the KeylessGo module in the spare wheel well was fried from water. I bought one off ebay that had matching numbers except the part number. Plugged it in after cleaning the connections and that did not fix it. When I grab the purple connector to remove it from the new module I can hear the module click and make noise. I have no idea what's causing the hatch problem so about advice would be greatly appreciated.
