Well, my mechanic knows Benz parts and found a new one. Says it is all working like it should. So, I'm heading over to pick up my Crossfire. Will ask about "look for signs of water in the lower rear hatch bay after you remove the trim and Styrofoam and unwrap the air pump module that opens/locks doors/hatch/and flashes lights. Water in there screws many things and gives ppl headaches".

Will update.
Thanks
