Default Moonroof reprogram?

Hi all,

I don't have time to visit the forums as much as I'd like to. Recently, I have had a problem with my moon-roof, this is the second time this has happened. Normally when you press the open button, the roof slides all the way open, slides all the way closed and sealed when you close it. It also opens when you remotely open all the windows. OK, for some reason it stopped doing that! You have to press and hold the open-button to open or close it, and when you close it, it won't seal right unless you tap the button just right as it closes. When you open all the windows remotely, the moon-roof remains closed. The first time it started doing this, I took it to my friend's independent Lexus service center (now defunct) and Lee did something with the button to reprogram it and the moon-roof worked as before. Recently it stopped working again. I don't know if I pressed something I shouldn't have or what! I assume that there is a way to reset/reprogram the moon-roof, just like there is a way to set the doors to lock - unlock when you shift the car into drive or park? What can I do to save an expensive Lexus dealer reset? My car is 2004, Levi/navi and loaded.
Many thanks,
Fred

AFAIK, the moonroof does the same thing if you disconnect power to the car as the auto windows do. They have to be 'reprogrammed' after power is reconnected. I believe it's the same method.

I just hold it down until it's open all the way, then hold it down to close it all the way and it'll start working.

Cheers,
Kermee
