Hi, recently I have problem with my RX400H. Many items have failed all at the same time. The list is.. No rear parking camera on screen, or guide lines. No right or left (turn) indicators. (Hazzards working) No reversing light. No climate control (screen blank) also the climate control switch and yellow on light does not work. Have tried looking for blown fuses but think it is something greater that controls all these items. Anyone's help would be greatly appreciated.
