Roof Not Functioning

Did you want to try to fix the roof yourself, or did you want to know if someone other than the dealer can fix it?
Do a search for "roof" by following these directions, you can skip the POSTED BY PART. You want to pay attention to the post that talk about tech stream & valet lockout.

We need more infos. What is the symptom? Red light flashing? Not thing at all? Half way? Won’t open, won’t close?

Thanks all. Closed the top, which has never had a problem, owned since new in 2002. The next use, went to open the roof and the switch was dead, nothing since. No light on the switch. Checked rear fuse panel (trunk) all were good. Cannot access other fuses, physically challenged. Switch feels strange but would expect some type of contact and not total failure. Not sure what route best to check to determine if /why power failing. Thanks for whatever help you
can offer.

The only way to fix it is to get access to "tech stream" and read the Toyota specific codes. The dealer has techstream, so do many Independent Toyota specialty repair shops and about 20% of the people that use this board.
Once you get the codes, we can help you fix the problem

You can also buy your own Techstream for $25 to $50 and diagnose it on your own, along with all the other many features you can use on the Techstream.

Try to díconnetc the battery and hopefully the system will reset itself. Be sure to check the valet switch and taunt over cover.

Those symptoms match a failed self check. The roof system has many moving parts that all have to be in sync to work. Before your car opens or closes the roof, it does an auto diagnostic of the system. If there is a problem, it won't attempt to open/close the roof. That way you it lessens the chance you will end up with a half open or half closed roof.
A non-seated trunk cover does a flash also, I believe.
Definitely check the glove box switch -- I think that would be consistent with no flash. Maybe someone/something bumped it.
And yeah, disconnecting the battery would clear the fault and let the system start fresh.

Except that the OP says no light on the switch at all. I was under the impression that if it fails diagnostic, the light flashes. Maybe someone knows for sure.

The system checks itself each time you push the button. It does not store the codes, so disconnecting the battery is not a definite fix,
A non seat trunk cover does create a flash, a failed self diagnostic doesn't cause a flash.

Tried it all and the only thing that changed was one short flash of the light on the switch suggesting that power to the switch is inconsistent. Ordered Techstream diagnostic that I hope will help as I can only imagine what the dealer will charge to diagnose the fault and repair. Hoping the issue is in the switch itself. Thank you for everyone's assistance. Still, the roof remains closed, switch not functioning, all safeguards/valet switch correct and battery was disconnected twice without any response. Lets hope Techstream helps.

From the description you gave, it sounds like your car/computer recognizes that your roof is in the partially open position. That is what causes the beeping.
There is a valet switch in the glove compartment. Make sure it is not on, or your roof won't work. Also make sure the trunk cover in the trunk is closed. Both of those will cause the conditions you described.
Once you make sure both of those things are ok, unplug your battery and plug it back in. Hopefully that will force your computer to figure out where in the closing stage you are at and let it resume.

Thanks for the info.
I was very concerned about programming. Presently I am tearing apart my car. It looks like water damage in controller. I will post info as i go through it.
