Our passenger side mirror met an unfortunate end on the side of our garage. I bought a replacement from a dealer and tired to fix this myself. I was able to remove the door panel to access the 3 bolts holding the mirror onto the van. I was able to remove 2 of the 3 nuts, but, as far as I can tell, the 3rd nut is darn near impossible to access. I've tried several different tools to get at it, but I just can't remove that 3rd nut. It is driving me, well, nuts! I can't figure out any way to make the access easier. Anyone with any experience in replacing this thing?
