Power mirrors, horn, cruise control and some interior lights not working.  Cruise does nothing, no light showing it’s on, map lights work with switches,   door lights work,  floor lights do not, none with remote illumination.  Nothing with the mirrors either.  I checked all the reduksr fuses. This is a 90
