How to take outbackseat lexussc400

There are two large clips at the front of the seated part of the back seat. Lift from the front-center section on both driver and passenger sides. Once unseated, lol, lift up and forward. Careful not to crack the plastic around the seatbelt connectors. Other than the four bolts at the base of the lumbar section of the seat, that should do it.

YES.... with out a doubt , it will stumble , won't idle well , sputters and eats gasoline, if you have 2 and i think yours dose have, you need to make sure if its the #1-0/2 sensor before the catyl. or #2 0/2 sensor after catyl.?? , & again, if you own a computer car , get the repair manual for that vehicle from your parts house, worth every dime you spend on it.

1992 lexus sc 400 When O/D is on, the O/D flashes

When your O/D flashes, It is indicating that your main computer "ECU" is receiving an diagnostic code(s). If you can get a code reader (stop by your local Autozone - they can read your codes for free). Once you receive your codes, you do your research on the codes. If not you can post the codes here and i will see if I can advise your further. GL.

1992 lexus sc 400 lost power after a burst of black smoke on right side, recently changed transmition, and regulator due to fuel smell.

I would like at the CATS, they can get clogged, this would also cause the gas smell in the cabinet. GL

How do I replace the ignition switch?

Your almost there. Look at where the steering wheel sets and the ignition switch. There will be a bolt to remove or not. ( I haven't worked on your car), No bolt, then look to the top of the switch. There is a hole there. You have to use a small punch or screw driver and push down, when the key is in the run position, then pull the cylinder out. Either way, the key has to be in the run position.

Why does my 92 lexus sc400 have a good battery but no power at all when cranked, all dash lights on but flicker when cranked. clicking sound from engine fuse box when cranked.

The clicking noise from the fuse box is the starter relay, that's normal considering the rest of the symptoms as it will stop working under a certain voltage like the rest of the lights and whatnot, then the voltage will rise again since all the accessories and everything turned off and everything will try to power on again, making the voltage drops, and so forth. If the battery is good and the car does this, then you definetly have a grounding problem. Either the connector on the battery is loose, or you have a damaged/corroded grounding strap/wire. Start by checking the connections on the battery to see if they are loose or not, and if they are fine, check the wire from the connection for corrosion or damage, and do the same thing for any other ground wires or straps and you will be sure to find your problem and get it starting like it should. The only other possibility which is VERY VERY VERY rare to see is a broken leed on the battery posts, which will not be visible since it happens inside the battery, but if you changed the battery recently or have tested with another battery, you can rule that out from the start and i'm 100% sure you only have a grounding problem.

Keys locked in trunk

Depending on the vehicle the rear seats may be able to come down, of course the the doors would need to be unlocked though. If the doors are locked as well all you need is a coat hanger and a wooden shim to unlock the door.
