Electrical problem
2004 BMW X3 6 cyl Two Wheel Drive Automatic 56000 miles
----------------------------------------------------------------
All of the three lighter adapters do not work and I feel that the fuse is blown. What and where is the location of the fuse box and which fuse do I need to replace. Do I need to buy the fuse at a BMW dealer, or can I find the fuse at an Auto Zone store? thanks, Stan

I am going to guess you don't have the owners manual. The fuse box is located in the glove box and the legend is inside the fuse box and it will lead you to the fuse(s)
