Question about 1990 Lexus LS 400

Open Question

Power Windows, Power sunroof, and radio all stopped working

I have a 1999 Buick Regal GS. I started the car, put it in drive, and the radio shut off. No clock, nothing. 2 Minutes later I went to put my window down, that didn't work, next tried the sunroof, didn't work. They all seemed to have gone out the same time. No fuses are bad. Is there something that supplies power to all 3 of these? (everything else in the car works)

hello freddy - the good news is that your lexus has a self diagnosis system built into it. this is what you need to do.

drive to an auto zone or similar autoparts store and have them put your lexus on their computer to scan for trouble codes. they offer this as a free service. with a little luck this scan will isolate the problem and the fix will be quick and easy.

if this doesnt fix it for you get back and let me know what codes popped up.

here is a link to the lexus trouble codes so you will have added insight. good luck.

Hi

Thanks for using FixYa. First of all you’ll need to check battery voltage, recharge it if it is low or jump start with another battery charger. Inspect, clean and tight both ends of all battery cables. Also check, clean and tight wiring connections. Check for voltage at relay. If relay has voltage but there is no "click" when key is turned to start, replace relay. Remove starter and inspect drive gear and flywheel teeth, replace damaged parts if necessary. Check to see if voltage reaches starter relay/solenoid when turn to start. If not, check for open P/N switch and brake or clutch pedal switch. Please pry the interior panel and release the inside door locks. If still the issue is not resolved then you’ll need to drill a two inch hole into the latch to access the inside lock link through the interior panel. After removing the panel replaces the latch to resolve the issue. See the picture where to drill---

Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

have you checked both fuse boxes, there is one inside the car and one in the engine between your battery and overflow tank, I had some light problems and found that one of the bigger fuses in the engine compartment was melted so make sure you check both spots

1999 Regal GS -stalls, starting trouble, won't shift now


the batt is suspect...take it to autozone, or other place, they'll check it out free......the shifting out of park is a seperate issue, the pawl for the steering/shifter is not working properly....did you notice if the steering wheel would turn when the shifter is stuck?....probably not....when this happens try to turn the wheel back and forth-not hard but not gently- a little graphite dust sprayed in there would help.......hope this helps you out

No power to radio, windows, or sunroof


best advices would be to check your fuses in the cabin or under the hood.

or

your grounding cable from battery or chassis is either loose or corroded. check your battery terminals and make sure they're clean. i had the exact same problem when relocating my battery from the front of the car to the trunk of the car. my ground cable was loose and the electrical circuit didnt seem to be going through the cycle.
