Hi new the Lexus scene I purchased a 2000 gs300 the other nice (lovely big car ) but after a 300 miles round journey the cruise control stopped working but the light is not even coming on , on the dash AV tried to find a fuse but can't find one as the only reason a could see the light not coming on is the fuse not working but any input is more than welcome cause at this point am totally lost
