One minute they worked and the next they were not.  My backup lights are not working on my '86 Weekender.  I checked the fuse and the bulbs.  All are OK.  It must be the backup switch and this brings me to my question.  Where is the darn thing?  I expect this is another reason to buy a Bently's Manual and your right.
In the mean time thanks for any help you might provide.
