I am having problems with the electrical in my car. My cruise control will not work, the rear view mirror will not show the temp and compass, and the accessory ports for my chargers will not work in the front or back (although the lighter works) My father thinks it is the body control module, but we don't even know how to find it. Also the vacuum hose is not getting any suction and we can't figure out why or if it is the reason the cruise control isn't working. Help is much appreciated.
