I don't know the answer to this, but it is something worth looking at. I believe its fuse number 25, but I might be wrong. A year ago, I started having problems with my gauge cluster in my 95 Ranger. I took out the fuse, and my odometer, interior lights, under hood light and speedometer all stopped working. I know this isn't what your looking for and I doubt it will help any, but thought I would say something about it.
