In an unrelated electrical problem. I had a Toyota Camry, lost all power to dash, electric door locks, windows motors, Kept blowing fuses. Sure I could trace wires. Getting to the wire bundles was a big problem. Gave up for a while, and one day I thought to search the Internet for Toyota electrical problems, Read some interesting problems and fixes, and one of those was to check the wire bundle by the trunk hinge for abrasion. Sure enough, I could see the copper wire that was causing all the problem. Secured it down to the sidewall, and everything was good.
