Thanks, yes I have the tools

 

Roof is working again!! An easy installation. About 30-40 min.
Thank you all for help and inspiration!!

 

Congrats and good job. Glad to see that you are up and running again.

 

Share a picture from the circuit board of the replaced unit. Strange how it can erode in that way. No moist or water in the trunk as far as i can see.

 

I have a 2005 sc430 bought new Years ago I saw on ebay a salvager selling parts off a 2005 like mine. he happened to have the roof ECU control box. I decided to buy it as a spare . It came with a transparent heavy gauge sheet of plastic that was held in place on top of the control module that was held attached with adhesive. I believe the plastic was there to protect the module from getting wet because the module when installed is just protected by the bottom trim panel. I find that I always have to clean my trunk from debris that falls in when the top is down. There also have members that have found there trunk areas wet from apparent roof leaks or clogged roof drains . If your replacement unit does not have this plastic cover I would install one to protect it
