About the rear plugs ,do a search here on the forum and you will find a couple of members that changed them. From what I remember you take off 1 side of the dog bone(motor mount on the top front of the engine might be 2 not sure) then take a ratchet strap and pull the engine forward a few inches and that will give you room to reach down and change them. Wouldn't you like to have 5 minutes in a room with the engineer that designed this or better yet have them change them !! Also the second part of your question the dic ? Are you referring to the overhead dvd player ? If so I guess you have to find out if its the player or the screen that is bad once you find out look to the junk yards for a replacement part . Try this link for parts.
