Lexus SC430 :: Nav Door Stopped Closing And Seat Memory Button Not Working
Oct 15, 2013
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.

I have a 2006 sc430 and have been having problems with the drivers memory seat although the passenger one works fine.
I have disconnected my batter for 5 minutes, moved the passenger seat all the way forward, heard the beep. Moved the reclining part all the way forward until I heard the beep, and the memory seat for the passenger works great.
I moved the drivers seat all the way forward, heard the beep. Moved the reclining part all the way forward until I heard the beep, but the memory seat won't beep (when you hold set and a number). I even replaced my drivers mirror (didn't tilt down due to bad motor), but that didn't work. Of course, I did redo disconnecting the battery and reconnecting it resetting both drivers seat and passenger seat.

On several other cars I've owned it was possible to link a key fob to seat memory. Meaning if my wife used her remote fob to open the car doors the seats and mirrors were set to her memory position etc.
I searched the owner manual and don't see this feature on our SC430.

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.

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.

Why External mirror command and seat memory don't work normally on my GX 470. Some time is work and sometime not. Maybe some fuse or relay are bad now...

Last week out of the blue, the lock/unlock button the driver's side door stopped working altogether. It's not stuck, as I can definitely feel it click when pressed. Also, the passenger side button works just fine. This is very annoying after spending a year without ever having to use the actual key fob.

Last week, the keyfob I had with me stopped working (no wireless functions). The light still comes on but I couldn't lock or unlock anything. I started the car thinking it might be some sort of reset thing and then turned it off. The keyfob started working again. I thought it was just a glitch until today when it happened again.
However, this time, no amount of fussing fixed it. I retrieved the second wireless fob from the safe. It too doesn't work.
Either this is a failure or the security system thinks something is up and is out of sync or something. I really don't know.
.One is around 2.7 volts. The other is 3.0 volts.

My power door lock switch in the drivers door stopped working (not the actuator problem, but the actual switch would unlock, but not lock the doors)
I started to research if it could just be simple corrosion and decided to spray the contacts with CRC electronics cleaner. It completely fixed it.
Next, my parking brake light sensor stopped working so I did the same and it fixed it.
I began to research cleaning contacts and found a number of people in the automotive forums who basically spray contact cleaner on every electrical connection they ever touch.
I will do this in the future. The only part I wonder about is if there is something better to spray on them to prevent further corrosion in the future. I used dielectric grease but it would be nice to just spray the thing down. However, CRC does say their electronic cleaner prevent future corrosion.

I have a 2006 Lexus GS 300 and about two weeks ago the key fob stopped working. I replaced two new batteries and nothing. I read up and found that if you place the fob over the start button and wait for the green light it would start. I have been starting the car like that ever since. Now here is the issue. Yesterday I went out to eat and when I was about to leave it would not start with the key over the button. I did not get a green light, nothing. after trying for about 10 minutes I got it to turn on the electrical system (basically it acted like it started but didn't) all the lights turned on and I saw the Check complete on the dash but the engine did not crank or start at all. Finally I disconnected the battery for 5 minutes and connected it again and was able to get it to start and drive home, now back to the same problem.

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...

I just got my car back from a body shop, after they fixed all the rock chips on the front. Now I realize the seat position memory is not working for both the driving and passenger seats. Not only the button does not move the seats, but I can't set the new positions into the memory either.

I picked up our ("our" means my wifes) GX last Friday. I'm a sports car and sports sedan guy. But I love buying vehicles, and I a huge car nut. It's a heck of a nice Luxury SUV with a lot of nice features.
One question so far. The web site specifically says the passenger seat position can be saved to the memory, but for the life of me I don't see how. Can it?

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.
