Hello,
I have a 02 SC430 and the top will not do anything. The car has been to a Lexus Dealer and they are clueless. There are no codes stored and everything is in place. I have checked all fuses, links, etc etc. The Light on the dash/switch wont even light up. I have a second car and have switched eveything you can think of short of the hinges. I have owned a few of these so I know how they operate. They normally dont break unless the car was hit or touched by a bodyshop. If anyone has any insight please let me know. Thanks
