My 2003 LX470 is having a wiring problem and it appears to be caused by a broken (diode) in the driver side view mirror. Problems are (1) both side view mirrors do not operate, (2) the remote key will not operate the doors, (3) power seats only operate when the vehicle is running, (4) the VCS and VGRS lights remain on and (4) the instrument gauges flicker upon start up. Is this all related to the broken diode wire or could there be more on? Is repairing the diode a DIY or do I need to take it to a shop? Any help would be greatly appreciated. Thank you.
