My lexus ls 400 heat or ac does nt work the light is on but the displays don't show check all fuses could it be the 40 amp heater control fuse

SOURCE: Fuse Box ( cover) diagram for a 95 Lexus LS 400 is missing.

check the wiring harness beside the hinge that moves when you close the trunk.i have seen the wiring get pinched and the ground gets broken. the tail lights have separate left and right side fuses.get a test light,and with the ignition in the on position,there should be power on both sides of all the fuses.the atc type have little test pins on them.ground the test light and put the tip on the fuse.if there is power,the light will come on. if a fuse does not light up the light on both sides,it is open.since the fuses are see thru,it is apparent if it is blown as the metal inside will be burnt.

SOURCE: I blew some fuses in my 1998 Lexus ls 400, i

check under the hood for more fuses.

SOURCE: Where can I buy a fuse that controls AC display

all those car parts stores you drive by every day, such as advance, autozone, NAPA, turns out they sell car parts, including fuses.
