1998 Lexus Gs 400 - Page 5 - Answered Questions & Fixed issues

your door switch could be stuck. remove it, there will be a black rubber boot covering it and I think is held in by a 10mill. bolt. Remove it and clean it it sounds like it is stuck.

I think, for this problem you have to go to the dealer. There is a few things that they have to do @ the same time. Also, make sure that you bring all of your keys to make sure that they all work with the transponder,good luck...matty

I have the exact same problem. Does it hesitate of the start and then take off? I put an OBD II scanner on mine and it is saying that it is the 1st gear shift cellinoid. Cost's about $350 installed.

before i would do that....check the fuse panel, if its electronic release.....

window motor is starting to fail you need a window motor Please rate my response thank you very much

Not Really. Once these Motors Start working Slowly, The only thing that will repair them is a Replacement of the Motor. Done quite a Few of them Through the Years. Please Rate my Solution, I need all the Help that I can Get! Thanks!

does it go off if u un-plug the switch? if u un-plug it and it goes out I think that you have a bad switch. hit a gunk yard and pull one out for 10$..Matty

you can reset your computer by unpluggin the negative terminal on your battery for about five to ten minutes. If you have a radio make sure you have the security code

Yeah, get the old lady out and push. (Smile)

well you have to take the spark plug wires off ONE AT A TIME only o you wont mess with the timing and then use a spark plug wrench and replace them one by one replacing the wire as you go

Your overheating problem is unlikely to have anything to do with a replacement starter. It's more likely that your car has since developed a radiator/cooling system/ head gasket fault

On most models the gauges get power from the same fuse the warning lights do. So it could be a problem with the printed circuit board on the instrument cluster.

change coils,tune up.

Usually a sign the coil is failing.The coil is a magnet with windings suspended in oil.

First of all you need to access the Suspension Electronic Control Unit (ECU) using suitable diagnostic equipment connected to the data link connector of the car, in order to pull out all DTC's memored. DTC = Diagnostic Trouble Code.
Then you will bu full informed about the root cause of the problem, and you will be able to repair & replace bad pieces and reset the Suspension ECU. Then the suspension height light will turn OFF, and you will have correctly height adjustment.
I suspect bad front or rear chassis height level sensor or bad supplly wires, but without scanning the Suspension ECU is hard to say. Anyway you can take a look under chassis at the front and rear chassis height level sensors & supplly wires, and clean all connections contact pins using suitable electrical contacts cleaner spray.
Let me know about found DTC's. I will kindly assist you to fix the problem. Good Luck!

depends on type fuse
mini
maxi
some also have screws that hold them down
locate fuse box under hood
remove cover
look for blown fuse, if NOT screwed in just pull straight up to remove, reverse to install new one
if screwed in just remove screws (righty tighty / lefty losy) reverse to install new fuse

You should be able to find the code by putting the key in the ignition and turning it to the on position (not starting the car) and then turning it off....On-off-on-off-on within 5 seconds and where your odometer reads should show the codes such as p1604 as with my truck

A code P0300 may mean that one or more of the following has happened:
Faulty spark plugs or wires
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector(s)
Burned exhaust valve
Faulty catalytic converter(s)
Stuck/blocked EGR valve / passages
Faulty camshaft position sensor
Defective computer

Possible Solutions:
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.

Hope helps.

Sounds like you have bad wiring or some other electric draw somewhere. You need to do a parasitic drain test, you have a hot wire somewhere, that grounds out and drains your battery, so the above test might not find it, if it is not grounding out when you do your checking.

Keep us updated.

There is something that is causing it to bind when it closes all the way. It automatically will open if it binds up. Check to make sure that it is not binding. You might want to grease the tracks that the roof slides in.
