slide the lower part of shifter handle down and you will find two screws, but there is 2 wires coming in from center console for overdrive button.you have to remove the center console cover and remove the 2 wires from connector and then pull up threw handle.when you go back together you will have to guide them back threw the handle.

Not too bad. Not much room, just enough to drop the starter. It is probably easier to go up through exhaust if you can get your exhaust shield off the manifold .

My hazards and turn signal lights do not work. I own a 91 lexus ls400! So far I've replaced the flasher relay under the dash. But they still don't work. Help please!

Have you checked fuses? Test them, don't rely on being able to see they're blown as they'll sometimes have a fine crack that's hard to see.

If you need further help, I’m available over the phone at https://www.6ya.com/expert/oscar_403cc49e0f00cda7

2000 Lexus LS400 Instrument panel fuse

It's more likely a fuse is blown, the tail lights are on the same fuse as the dash illumination, check the tail lights if they are not working replace the fuse marked 'tail' in the fuse panel on the inside at the left side of the dash under the cover. At the same time check the 'gauge' fuse', there is a fuse location diagram on the cover.

I had the same problem with my 1992 LS400. My Lexus mechanic fixed it by replacing the MAF(Mass Air Flow).

This used to drive me crazy when the weather was hot.

Where is the computer box in the Lexus LS400 located?

There are 11 electronic control units(ECU) located in the dash area. They are as follows.
Engine + trans. ecu. behind right side of the dash.
Abs + traction ecu. beside the engine ecu.
electric mirror ecu. behind upper right side of dash.
SRS ecu. behind dash at console.
Shift lock ecu. in center console near shifter.
Power seat ecu. under drivers seat.
progressive power steering ecu. behind left dash left of column.
Steering column tilt + telescopic ecu. behind left dash above column.
Anti-theft ecu. behind far left of dash.
Cruise control ecu. just below the anti-theft ecu.
My guess is you are looking for the engine ECU but you may be
looking for 1 of these in the future. Hope this helps.

As mentioned check ps fluid. If it wines when turning and still no power then the pump is internally bad.. If the fluid is dissapearing fast then its a hose or most likely a leaking rack& pinion assembly..
