Default Retractable Top: Trunk Opens, but no more

I have a 2002 SC430 and the top is not retracting when I try to convert. When I push the button, the trunk comes up, but then the top does not retract into the trunk. The button displays a solid red light, not blinking. There is the slightest of movements by the top, opening about half an inch that I can see when looking from the interior, but then it just stops. I hear no strange noises and an inspection of the mechanics while it is operating reveals nothing that I can see. I tried the valet button in the glove box but that isn't it. Any ideas on what I might try or what I can expect when I invariably bring it to the dealership?

Some things I'll try when I get home tonight (let me know if this isn't worth while, or if there are others):

(1) reset ECU by disconnecting neutral on battery terminal
(2) manually opening the top

Unfortunately it is about 6,000 miles outside of warranty now. Thanks in advance.

Thanks Bacardi. The "not cheap" is what I was worried about. I extended the warranty out as far as I could, and then this comes along.

Just to add, the trunk goes up and then back down smoothly with zero problems when I press the button. It is when it gets to moving the roof back that it has issues -- stops at the exact same point each time (about one inch slid back).

Just when nice weather is beginning -- what luck.

Disconnecting the battery is always a good first step.

After that, decide if you are the type of person who is willing to fix things yourself. If so, the next logical step would be to get the DTC code which will identify the problem. You have to do that at a Lexus dealer, they will charge you for labor, and the fault has to occur while the DTC code reader is attached.

Check out this thread for a similar problem solving procedure, although obviously the actual problem in that thread is much different than yours.

Just to clsoe out the thread, my wife (it is actually her daily driver) took the car to the dealership and they confirmed that the cable was off track. The cost was $300 to fix it ($100 for diagnostic, which rolled into the price). Crazy when you're happy to spend $300, but I'm just happy it isn't something more major.

Any chance of posting a pix of the area you are talking about? Sounds like preventative maintenance time!

Studshark, be sure to check your trunk lid struts first. If they will no longer hold up your trunk lid when you open it, they might be the problem. My struts went out and then my top would only intermittently open. Just like yours, my trunk lid would open and then the roof would only move part way back. At least it would close without issues. The problem went away once I replaced the struts.

Good luck and let us know what you find out.
