1992 SC 300: No power to radio or power mirrors (which are on the same fuse). Fuse checks OK for continuity, 12 volt power on both sides of fuse when checked with volt meter. Both 12 volt and ground is OK to amp and CD player in truck. Mirror motors have power and will work when actuated by seat/sterring wheel/mirror memory buttons but will not work when try to adjust with regular adjustment switch. Radio has no display, power antenna will not work. Any ideas.
Thanks -

 

Well, had hoped someone could have offered some advice on this or similar problem. Have an appointment w/ Lexus dealer Wednesday. $$$$$$$$
