I used my sunroof on my 99 STS. When i closed it it make a clicking noise and was difficult to finally get shut. Then, when I shut the car off, there was aabout a 5 sec delay and the sunroof automatically opened about 1/4 of the way. I repeated the effort and every time I shut the car off...the sunroof opens now. I pulled the 2 fuses for the sunroof while it was closed....but, as soon as i turn off the ignition...same thing.
