Amen to they get lost. Ever see the sign that says OUR MECHANICS have 450 years of experience and if you were to divide that by the 60 mechanics they have well you get the picture. Anyway I looked and couldn't find location of the GEM on mine but will refer to the chiltons shop book in the morning before I go to dealer. It just seems that fixing one problem only created 2 more? It'll get better but I'm going to call him out on cost of sensors for the door ajar seems he's aboout twice as high as a dealer on the net and no shipping charge. Thanks again.
