all ligs go through integrated power module so have a pro scan for that. the mirrors go to the same thing then to driver door module so either could be screwed up. so it will need scanning by a pro not auto parts.

under hood lh side and it has 3 fuses in it. you can't change it because it has to be programmed to your vehicle a pro has to do it with a scanner. it controls many things besides the lights and mirrors.
