Electric solenoid is bad in the door.

have the fault codes read to see if it comes up could be a problem ECM unit that is shorting out when a component over heats and blows the EFI fuse

Contrary to popular belief, the battery light can be on even if the battery and alternator appear to be working fine. It is located in such a place as to indicate effective charging. What that means is that even if the battery is good and the alternator is outputting voltage (and current), the lamp lights to indicate that the vehicle is consuming more power than the alternator is producing. This is important since once running, if the alternator cannot supply all the vehicle's power needs, the battery is drawn on for the remainder, and will suffer draining as such. Most manufacturers provide alternators that produce more than enough power to operate their vehicles, but many owners add additional high-power audio systems and other items that can overwhelm the factory unit. You said the alternator was "tested"....was it load tested, or did they simply hook a voltmeter to it while the engine was running and saw 14.5 volts? This is important since a failing alternator may regulate its voltage properly, but may fall far short of the output current (power) needed to operate the vehicle. It is possible that there could be a defect in the battery amp circuit, but it is such a simple circuit that I would be more suspect of a charging system issue than I would of a faulty battery light. And no, there is no reset for it - as soon as the power balance returns to the positive side (car needs less than is produced), it will go out all by itself.

Kick down is a cable. Look at the throttle body. This is usually where the cable breaks. Small plastic clip that hangs on a post.

Check for power from the supply to the thermostat, to relay, to AC

Probably a loose or corroded connection in the master window switch. Sometimes if a window is down when it is raining the switch will get wet and cause some corrosion on the contacts.

There is a pressure sensor in the gas tank that isn't working correctly. The engine will not run correctly without the battery because the alternator will not produce voltage for the electronics or the fuel pump.

The pump is inside the gas tank. Only Ford products us an enertia switch.

Sorry Scott no inertia switch , Two relays , circuit opening relay an the other is Engine main relay if the wiring diagram is correct , hard to tell ! Japanese wiring diagrams ! go to www.bbbind.com free TSB'S an Wiring diagrams .

Hi Pamellaa to reprogram the sunroof do this procedure Good luck

Also Known As Vehicle Speed Sensor usually held down w/ a small bolt on the transmission case speed sensors on transmission Club Lexus Forums read the following thread by car owners of your same make / model! they even included pics of the sensor

the car has tail lights the correct name is PARK because there are many park lights not just 2 i there rear.(like days of old) Tail word is obsolete today. no problem but is key fact to diagnosis, (20 odd lights and complex) check all park lights, even the front. are all dead, and side mark lights (if opted) and license plate light and all dash parking lamps called , Dimable Illumination. check fuses yet, (test them)

Your question does not make any sence

Do you have a bad connection to the speed sensors, what are the symptoms? Does this help? https://www.youtube.com/watch?v=wpgC9Nf812s

this a rear wheel sensor. Hope this will answer your question,If do pls click on helful botton and you can follow me at fixya,so I can answer your question faster.thanks.

Yes. Thanks to Dennis Weid, Robert Garcia, Colin Strickland, and "gingo12670" on this website, that is what I found to be the problem causing my 2000 ES300 to not shift more than once into overdrive without shutting my car off. Apparently if your knock-sensor(s) is bad it will send a signal (or lack of an expected signal) that will cause one of the "brains" to not allow a shift into overdrive since that would only aggravate a knock situation. The sensors are not an easy fix as the intake manifold must be removed. It cost me $750, but I am happy as a clam since the solution has eluded me for too long. My Lexus has over 200K miles but after flushing my transmission to no avail, but just now replacing both knock sensors, it now feels once again like a new car.

light is sitting in line on the hot wire. If you want to blow the fuse, tough the side of the bulb to any chassis metal.

check that the light is not referring to the hand brake adjustment as well
