Lexus SC430 :: Passenger Window Control Failure
Jan 23, 2016
At the 150K mile mark electromechanical components are starting to fail (Nav DVD reader, CD changer, 2 starters (they seem good for only ~70K miles), brake switch, etc.) which is probably reasonable to expect, even in a non-humid climate. Recently, the controls for the passenger side window stopped working. Some details:
- Driver's side window control works to control driver's side window
- Passenger side window switch LEDs are not lit on either door
- Passenger side window rolls up and down when top is changed to up or down position
Given that the motor is proven good by the fact that the window goes up and down with no problems when the top's position is changed, I'm inclined to think that there is probably an issue with the "COMPUTER MPX DOOR" component in the passenger door.

My passenger side window won't roll down. Everything else on the door works including the mirror. Guessing the motor, is there a way to check it?

I just tried to lower my passenger window, and it was completely dead. Driver's side works fine. Tried both the switch on driver's side and passenger side. Neither worked to lower passenger window.
Popped the hood and swapped out Pass & Driver's fuses. Pass side fuse is ok - ran the Driver's side ok.
Dropped the top and both windows ran down and back up ok. I'm guessing connection in driver's door(?). Maybe that switch for passenger window is bad?

All my windows work, except my front passenger side window. It will go down, but not up from the driver side switch. It works from the passenger side.
I did NOT replace my battery or lose power. It started when I was driving and wanted the window half way down, but it kept going fully up or fully down. I finally got it to where I wanted it to be, but after that i could no longer bring it back all the way up. It can go all the way down, but no longer up.

I am a newbie Gx470 owner. I just finished a timing belt job on my 2005 Gx470 with 127K on the clock. After the work, the driver's master window control would not activate any window but the drivers. On a recent outing my wife activated the passenger' window. I suddenly regained control of that window from the drivers position. You guessed it, when I ran the rear windows up and down, I regained control of them also.

So the two windows on the passenger side have fallen and can't get up. These regulators you gotta buy to fix the problem cost a ton, and just as much to have installed. Why on earth can you not buy the little plastic brackets to fix the problem instead of the whole regulator? If there IS a way to buy these brackets, it would be keen to know...

2 days ago my auto window down and top not working (top up and down), light on button for convert. Top not on when pressed. My question is does the auto window down would that make my top not operational? Because the same day my auto window down stop working, my top stop working the same day. Both of my window can still roll up/down when I hold the button up/down.

Any fix for the driver side window rolling up slower than the passenger side. Sounds like the motor is having a harder time moving it. I can hear the motor straining. Looking for info about successfully lubricate the regulator and fix this? I'd like not to have to replace the motor.

I guess the roof needs adjustment since my driver side door won't close if the window is up all the way.
Checked the roof and found there is a larger gap on the passenger side than on the driver side. That causes the unevenness of the roof, I think.

I've had a squeak, for lack of a better word, in the back seat near or rear window. I couldn't tell if it was the rear seat back or something else.
I began lowering the roof and stopped the process by turning off the ignition while the roof was just setting down in the trunk. This leaves the raised covers pointing up vertically to let the roof pass. (When the roof is up these covers form the rear "package shelf".) In the center of the car just under this cover there is a round black rubber bumper stop the size of a 50 cent piece (whatever those are). This stop is adjustable up-and-down. Rotating it counterclockwise raises the stop and clockwise lowers it. I raised my rubber stop, by hand, a couple of turns upward.
That's all. The squeak is gone. This bumper apparently bind the package shelf to the roof when it is up and stops if from moving around - and squeaking. I don't know the Lexus method for adjusting this bumper stop but a turn or two made a wonderful difference in my mood today.

When you close the door and the window is down, the window glass sounding like it is rattling when the door shuts? I am wondering if that is normal for 430's or if there is something missing or broken in my doors. (They both do it)
I don't really notice it while driving but it makes my skin crawl every time I shut the doors. No sound as long as the windows are up.

Air suspension stay on HIGH position, the SELECT button is showing on NORMAL. I try to push UP or DOWN, the green led indicator doesn't respond, just stay at NORMAL position and NO flash at all.

I've tried searching, While I can find instructions for changing these valves on other cars, I can't find it for the SC 430.
Is there a link here for how to do that? I think my filters are probably clogged (165,000 miles) but I can't figure out where they are.
I'm thinking it may be why my VSC light is on as well. Should I try Seafoam in the crankcase first?

I'm the owner of GX 470 2006 85 k miles, facing a problem of height control failure. The problem started some few months ago while starting the car. I there was a noise behind on the height compressor. Took it to my mechanical and the noise disappeared because the compressor wasn't well fixed to the body. Since then i'm not able to adjust the height of the car. The car remains at the height low level and jumping dangerously each time i drive it inside a hole. Decided to go back to the mechanical the following code error appeared during the diagnosis: P1445. How can this code be related to the height control system when we know that this code is related to the secondary air injection system switching valve?
I decided to change the 2 height sensors located on the R and L rear side of the vehicule and the VSV locate in the engine. The problem remains. Now the dashboard keeps the green light at N and the button to raise and low the height of the car is not responding. More the mechanic can't anymore obtain the errors code from his diagnosis device.

The outside temperature has been cold since the purchase of my 07 SC almost 2 weeks ago (below freezing F ). The A/C green light has not been lit. My 05 SC, the light was on all the time. Dealer says the system will turn the A/C off in certain circumstances in very cold conditions.

On my 2006 SC430 the DRL's come on with the low beam lights.I assume this is standard across all second Gen SC430's. My issue is the passenger side DRL went out. The high beams worked fine, but only the drivers side DRL would work when the headlights are on (no DRL's come on with the headlights off).
So, I went to AutoZone and picked up replacement bulbs. I just put them in and the exact same thing is happening. Brights work fine, DRL only works on the drivers side. Where to even look now that I have replaced the bulbs.

Unfortunately my car Heater A/C Control Panel LCD is broken, I mean only the screen. I accidentally hit the screen while I was pulling my guitar from the back seat .It shows many black lines that are almost covering the whole LCD!! everything is working fine except nothing can be seen on the screen.
I was told that I must buy the whole panel and it is really costly. I thought maybe I can replace only the screen? Is it possible? Or can I get any other car LCD and fix it into this panel??

VSC, VCS OFF and Check Engine Light .... all came on a few minutes ago while out for a Sunday afternoon drive. Depressing/releasing the "VSC OFF" button multiple times did nothing. All 3 lights now stay on. Checked the manual which said to take in to Lexus dealer asap but could continue driving....something about vehicle stability control system not activating.

Well I cracked the clear plastic lens on the AC control unil while removing it to replace the factory radio. Where I can just get the minimal parts to fix this? Seems all I can find online thus far is only replacement of basically the whole control unit.
