97 Camry electric mirror problem

I replaced the pass. side door mirror on my 97 Camry. Spliced the wires rather than remove door panel to connect. Mirror worked on first test. Now neither pass or driver side mirrors work. Fuse is fine. No power to fuse block for this fuse. All other fuses in the block are powered and working fine. All other accessores seem to work. Any ideas? I have no clue where to start. I know it will cost a fortune if I have to take this to the shop and have them torublehoot it. Thanks for your consideration. Jackie

If the fuse for mirrors doesn’t have any voltage on it then you most likely have blown a different fuse ahead of that one. Have you checked the panel under the hood for any bad fuses?
