Yup! did all that. Fiddled with the partition (the switch was replaced) Made sure the trunk was shut good (By the way, I love my car but the trunk lock is a very bad design! no rear key lock, no inside trunk release) Only way to open it is with the door locks or the key fob! If your door lock module goes out, your screwed because its in the trunk! Happened to me! Dealership had to take parts off to get to open the trunk. So I had the panel relay and the door lock module thats in the trunk replaced and all worked great for a weekend and then stopped! doors wont lock/unlock and top wont go up or down! They scratching their heads at the dealership, because its not throwing codes. Only thing thats left is the Body control module under the hood. eith that or maybe the partition switch be adjusted as some say you can do, or the handle on the roof to pull it down. Very frustrating!
