Lexus SC430 :: Trunk Lid Opening But Top Not Folding
Apr 17, 2015
Today I tried opening my roof... The trunk lid opened but the top didn't fold.. I closed it... After restarting my car I realized the front switch for the top doesn't even light anymore...
I unplugged the battery... replugged.. the switch opened the trunk lid again but top didn't move and switch was a solid red light... once I pressed closed, trunk lid closed and switch stopped lighting after (not responsive). What it could be?

Other than checking the fuse and the valet switch, anything else to look for when the trunk will not open via the key or the dash switch? The car does make the beep when the key remote is pressed, but no open. Also, the top works fine. Gas door works fine. Manual release of trunk also works.

I am a new owner of the 2007 SC430. I wonder how reliable is the roof folding in the SC? I heard that many SC having a either mechanical or problems or electrical problem after a while? Is that true?

When I first got my 2006 Lexus RX400h (LOVE the car, btw), I would unlock all the doors by clicking twice on the unlock button on the key fob, then hold it down to open the trunk.
My dad went to get something from the trunk and I gave him the same instructions. Well when he did it (we were in the middle of a rain storm) all of the windows opened and not the trunk. Now this is what happens every time.
I'm not sure what happened, but I'm really missing opening my trunk through my key fob especially when my hands are full. Why this is happening and how I can open my trunk using the key fob again?

My roof will not open. When I press the button, it only opens the rear trunk and could hear the roof motor unlocking functioning, but will not open. It only opens about a couple to few inches and stops. It seems tho it's going to open, but gets stuck.

Sometimes after opening fully, my trunk drops down again about halfway. I cannot think of any logical explanation for this. Moreover, it doesn't happen all the time. But the occurrences are pretty unpredictable. I took the car in to my service dept. and the trunk worked flawlessly. But later that same day, it malfunctioned. It makes a noise as it drops and comes down at a rather fast speed. In fact it's rather scary because if it didn't stop about half-way, it could be potentially harmful.
This happens even when there is no-one near the trunk.

I have a 2002 SC430 And its the second one I've owned. And for the life of me. I can't remember if the side windows lowered a little when you open the doors. The past five or so cars I've owned did. But this one doesn't.
To clarify. The windows (Both driver and passenger) Would drop about 1/8" when you open the doors and raise up once the doors are close. is it normal that the Sc doesn't do this?

In an earlier thread, I talked about my roof stalling at the end of an opening or a closing operation. I just returned from a 260 mile round trip to the Lexus dealer to address this problem and get some other maintenance done..
To recap the problem, the roof appears to complete the opening or closing operation but won't finish it by turning off the red light on the switch. The switch then won't respond to either open or close. The roof stalls. It does this about 1 in every 10 or 12 open/close cycles.
Of course, if you drive the car with the red light still lit, you're treated to a chime when you go over about 5 MPH. Also, your trunk is locked.
I repeatedly re-try the switch of course, but without success. I eventually restart the car. Either the switch recovers or restarting does the trick, because so far I've been able to get the switch to work again. I would assume the stall will eventually stop being intermittent.
So, I talked with the Lexus service tech and he said he is very familiar with the SC roof. After hearing the symptoms, he quickly diagnosed a failing proximity switch. He was confident they could diagnose the problem.
So, I was due for the timing belt replacement and decided I'd have Lexus address both issues.
As I suspected, they need to catch the roof stalling to diagnose it. And guess what: They could not get the roof to stall. When the tech called to say my car was ready, I was disappointed my roof could not be fixed. The tech really did not know much about the proximity switches, like how many are in the roof. When I asked, he said replacing them all would be expensive and they did not believe one switch could be identified as the culprit from the description of symptoms.
So, here I am back 130 miles from the dealer with a tricky roof. I am thinking I will find out whether any local mechanic (Toyota or an independent) can find and fix the bad switch when it does fail.
Fortunately for the rest of you, the tech says this is not a common problem. I am aware of the manual operations to raise the roof, but really hope I don't have to go there!

The shocks (or whatever) that keep the trunk open have gone bad. Of course it happened a month after my warranty expired. They look easy to replace. Where to get them, cost, and how to install? I don't like going to my Lexus dealer. They make me feel like a criminal for not changing my oil every 5k, changing my own filters, etc, etc. etc.

I am trying to replace the trunk lights in my 2006 SC430. How do you remove the light covers? It seems like they should just pop off, but reasonable amounts of pushing and pulling has produced zero result. I don't want to break it.

'02 sc430 here and the oddest thing started happening this week. The trunk will not open when using the button on the driver's side. Push the button and I don't hear any activity. But if I use my key remote the trunk pops open as usual. At the exact time this problem started happening, the top stopped opening as well. I pull the cover back as usual in the trunk, make sure it clicks into place, but when I push the button to open the roof, it just flashes red on and off over and over as if the latch is not in place in the trunk. How this all started.

I am getting water at the very front of the trunk, nearest the passenger compartment. Might be the drains in that vicinity that might be plugged causing an overflow there .Rest of the trunk is dry. The only wet area is immediately underneath the pull-out "shade" thing that has to be in place for the top to operate. Some indication that the water is coming from above that, since it is wet also.

When I push open for the convertible, nothing. No light no warning nothing.

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?

So, last night I was driving with radio off and a "whirring/fan" sound was audible in the rear of my 2002 SC430 - a sound that I have never heard. The sound seemed to resonate from the driver side, access panel (which I believe holds fuses and other systems for roof). After the vehicle was stopped and restarted the sound continued. Now today, I insert the key into the ignition - no sound; turn to accessory - sound is audible; started vehicle and did not hear sound. Second time I repeated and sound was heard; started and did not hear sound, Third time I repeated and no sound heard in accessory start position. What the heck is this? Any diagram of the trunk and what components are housed in the center bay? Does this vehicle have any auto-leveling function that activates?

keep finding a small puddle in the drivers side corner of the trunk no where else just in this removable pocket. Under it is a flap type of thing which goes into the inner rear wing is that for ventilation. Could water get in from there ?
Can't find any drips from the trunk lid all the seals look mint.

Can I use my key to open my trunk in the case of a dead battery? I disconnected my battery last night to try it out, but it wouldn't open. Some people say turn the key 50 degrees, but I don't think my key will turn that far. I was also scared of snapping the key off in the lock.
