convertible top problem
when it is only a switch ?!?!?!?!
Not cool, not cool at all.
Folks we NEED to source these switches some how
If the trunk is open, even slightly, a switch tells the computer that the trunk is open and prevents the top from going down. If you bypass THAT switch (there are probably 12 or so switches) and have it in a closed state all the time...the computer will think it is ok to drop the top EVEN though the trunk could actually be fully open.....I GUESS you could be mindful to check the trunk for a proper state before trying to drop the top.
Someone NEEDS to start a business repairing these things without having to buy a whole assembly.
I should qualify this answer. I believe in doing things right, but fear I don't have a great choice here. I am going to search for the right switch, but bypass might happen. We purchased this vehicle a couple years ago, 16K. The deal wants 12K to fix this. I am also a finance guy and that is a brutal "equation" there. I talked to one other place that said they would charge close to the same. Not an attractive job or margin for them. To do it correct with the new assembly you have to take most of the body (o.k., trunk, roof, seats) out so just saying.
I always appreciate a job well done, so any advice will be listened to.

Definitely need a schematic to spell out as to what each switch does. Did they tell you what code or switch is the problem?

FWIW in the photos, you see a flat tray-like plate. This is a separate part, # 64361-53020, that sells for $900. So what you see in the photo casts around $5000 new.

can you send me the link where you bought the manuals...I'll probably need them in the future for my daughter's car.
I really like the car...but damn, these parts
I believe I have corrected the issue, I will create another post in the hopes this can help someone else. After ordering the manuals, putting in a patio in the back yard, a short vacation, fixing the VW (vacuum hose) Jetta, getting the manuals and more research, I finally got around to dealing with this. The fix (cleaning a switch) has been good since Saturday (so nearly 48 hours), turned the car on/off at least ten time, about five drives, we hope to have our car back without the warning, without the bell constantly going off. Procedure in next post.

Knowing how to open the trunk from the inside of the car is nice. There is a tab between the back seat head rests, pry up gently (I used screw driver covered by shop cloth), use hard/manual key to pop the trunk.
My idea was just to find the switch diagnosed and try to clean, if that didn't work, replace.
Open luggage compartment
Step "2" above, the manual shows the "emergency release cables", those are in the body of the car at the very back. You can see one of the hooks in this picture.
On the second page of the manual it shows how to lift out the luggage compartment door (trunk) and it notes this is a two person operation, it is. My wife helped me. I saw someone with a smaller Lexus do this by himself, with shims, but that doesn't appear good for the mechanisms. This was not easy, but not too hard. We had trouble getting started as you need to pull those yellow hooks, get the hinge out of the set position, and then start pushing, pulling, etc. the truck up. The diagram does give a good illustration of the path you follow to get it up and out of the way. I followed the manual further for a while taking off trim pieces, but for this issue, you don't need to do that. Get the trunk cover out of the way and you can get to two switches (left and right)
I found the switch, the area artistically pointed out in this next picture. This is the left hand side, from what I could tell everything was mirrored on the right.
Closeup of the switch (I neglected to take any numbers off this)
I cleaned between the contact and the arm. I used rubbing alcohol (I am sure there is something better) and a metal, pliant, clean straw cleaner (something you would push through drinking straws to clean).
This next shot shows the reinstall, I thought it considerate there was a space in the gear to get to the switch.
As noted in previous post, this appears to have worked (knock on wood). The warning is gone, the roof works, and we have driven around for the past two days with anticipation every time we turn it on.
