Lexus SC430 :: 2002 - Nav Screen Stopped Tilting Back And Door Won't Close
Feb 5, 2015
A couple of weeks back out of the blue my Nav screen stopped tilting back and of course if it doesn't tilt back the door won't close. I did the Lexus Diagnosis on the Tilt and Close Switches and it turns out to be something in the 'Nav' unit. Of course Lexus doesn't sell parts for the Nav unit... just the whole thing.
Since that time I have spent way too much time on diagnosing it and I actually tried another used unit that has the same problem as mine. What I think that I have figured out is that the motors are ok but the control unit, a small circuit board within the nav unit has failed. The problem is that this unit has 2-3 IC chips on it and any way to repair this circuit board.
Any luck repairing these circuit board or am I stuck.... The I was able to retract the unit into the dash and the door opens and closes but it would be nice if it tilted as they had intended...

At first the drivers side, side mirror would tilt as it should when backing up but when i got onto the street from my driveway wouldn't stop tilting up-words till it made a clicking noise that it wanted to keep tilting but couldn't. The only way to stop it was to adjust the side mirror manually and tilt it down and it would stop and stay at whatever i set it as. Now it just doesn't tilt at all.
What part numbers would i need to fix the problem? I drive a 2002 SC 430.

Our car was rear-ended (we had a great shop to the repairs and the car drives/looks like it did pre-accident). However, the navigation door magically stopped working now that we have the car back. The navigation screen still works fine, but the open/cose buttons will not make the door/lid open.
On other threads I have searched here, people have suggested this could be from the door being off-track (not the case here), a broken motor (could be the case), and/or a blown fuse (also could be the case).
What fuse I would need to check if it is in fact a fuse? I've looked at the fuse boxes in the engine bay (by the battery) and in the trunk, but all fuses look fine. Is there anywhere else I should look for a fuse before wasting a day at the dealer to diagnose/fix the problem?

Diagnosing different minor problems with my sc430. Tthe lastest one is that my navigation screen will not tilt back so the cover will go over it. It seems like its tilted forward all the way. The screen still works and all. But the tilt button does nothing and its too far out for me to get the wood grain cover to go over it. Is this a common issue? and whats the remedy?

I just bought a 2002 SC430, 62,000 miles, silver/saddle near perfect condition on owner, all records for $17,000. The radio door is stuck open and won't close. How to fix it? [/COLOR] Also the radio antenna will not go all the way down - about five inches stays up. Are the two problems related. Like others mentioned, I could eat off of the engine and the trunk still smells like a new car.

Yesterday I noticed my nav screen stopped responding but partially. It'll let me press buttons on left side but not right side. Unfortunately the "I agree" is on right side so I can't even get passed that screen. I don't use the nav but I'd rather have the map showing then "Caution...."

I just got an 02 SC430 and I am going through a few things. The Nav screen works fine but is frozen in the rear tilt position. I would be okay if it were frozen all the way forward???

The navigation door stopped working about 6 months ago while the navigation screen still worked fine. Two weeks ago the door started to work as it should be, but today it stopped working again.
According to other threads people have published this could be from the door being off-track, a broken motor, and a blown fuse. Obviously none of these scenarios could be apply in our case.
Btw, I checked all fuses and could not find any problems with them.

Got an interesting electrical issue on my 2004. I'm not sure if the issues are related but they happened at the same time. About a week ago the nav door stopped closing and the seat memory buttons stopped working. When you press the close button the nav screen moves back but the door never closes. The seat memory buttons on the door don't work either but the seat adjustment controls do work. When adjusting the seat position, as the seat moves moves, you hear beeping. It sounds like the same beep that you hear when memorizing a seat position. I checked and tested all the fuses they seem to be good.

Just picked up a pretty nice 2002 sc430 today. On the drive home I realized all the dash backLights are not lighting up. However the The radio and climate control unit do have a dim backlight working but is stuck at one level of illumination.
Like most cars the all dash lights should be very bright during the day and when you turn on the headlights they should all Dim down. ..... Not on this SC.
Makes no difference what position the headlight switch is in....Nothing changes or lights up
and
The little Dimmer does nothing either when turned all the way one way or the other.
Fuses? I am not sure what to try.

My navigation door quit working, tilt function also, and it's stuck open. The Nav unit works fine. Dealer is telling me thousands to replace it - but I suspect it's like the Mercedes dealer where my SL was missing a $10 clip - and they wanted to replace the dashboard... I'm hoping it can be repaired. It makes a little "ping" sound then I turn the car off, but I don't hear the door motor.

Whats going on with my 2002 SC430. Every time someone (valet) puts the key in the door to unlock it, the car completely shuts down. The remote won't work. The only way to get it going again is to have the door popped open. This sets off the alarm but once the key is in the ignition and started, it's all good. What is going on and how to correct this?

I've been trying to program the remote on 2 keys. With the sequence found online and in this forum, I did the insert/remove several times with no success. I then tried to turn the master key ON/OFF TWICE, which erases all the other remotes. Still did not program the new key, but now it seems to have affected my door lock buttons in the doors.
When I hit the lock buttons inside the car, the lock is sluggish, and I cannot repeatedly lock/unlock from the door switch. The second or third try gets a dull thud and the door lock only moves partially into the lock position.
Is it possible to reset the door locks so they again click in place with a nice, beefy motion?

2002 sc 430--interior door latch cable is broken at the ball. Is it possible to (purchase and) replace just the cable or is the cable integrated with the locking mechanism, requiring replacement of the whole unit. Also, need to get just cable and/or integrated cable/lock mechanism.

So maybe it is just my incompetence on this.... however, I was putting my second tank of gas in the 2016 and the Fuel Filler door will not shut...
Not only that but since the door will not shut, on my dash screen it keeps saying "Refill Ready" every 5-10 seconds.

Locked my keys in my car. A locksmith came and instead of using the tool to unlock using the unlock button, he just pulled the regular lever inside with the tool to open the door while it was locked. Since then I cannot open the driver's side door from the inside. It will open, lock and unlock fine from the outside. It is unlocked when I attempt to open it from the inside. I pull the lever and nothing happens. I have to unroll the window and open the door using the outside handle or crawl over to exit from the passenger side door.

As the title says....sometimes the trunk does not latch unless I close it hard. Is this normal for a SC? Why?
I took some pictures of the hook and the latch so what is wrong:
First, the hook:
A couple of views of the latch:
I cannot tell if something is wrong....other than a slight dent on the outside perimeter of the latch housing?

Top won't close,the button seems to be dead, my question is can you replace the button that opens and closes or do you need to replace the whole climate control panel. There are no codes that show up. When I press the button down the windows go down but no top working, package tray in the trunk is closed and luggage button is off.

So i haven't used my top for awhile because it's been really hot in texas. I tried it for the first time today and I can't even get the open close switch to blink red? I did a ecu reset by unplugging the battery for 30 minutes nothing. I check the fuses in the trunk and they were all good. I did install the VIas awhile back but I don't think it could be the temp control? I'm assuming if it wasn't plugged in all the way the AC and other functions would not work.
