I have noticed when opening it, it stops about 3/4 way open, and then if you hit the button again it goes all the way into the roof. When closing it always has closed all the way without having a second stop. I cleaned, lubbed, and adjusted the screws that hold the glass to the frame, as the glass panel was not lined up with the roof properly when I first got the car years ago. I've done the same thing on one of my SHO's. It's worked fine for a few years. Can you tell me more about where the relays are located for this? Doubt I am overheating it, I opened it, and 20 minutes later tried to close it with no luck. Tried the switch several times, no luck. restarted the car and drove a short distance, and tried it again, and it worked. The relays sound very likely.
