My sunroof has stopped operating, so naturally the 1st thing I looked for was the fuse. As I thought it was fried, so I replaced it with a new one then I turned the key to the on mode, as soon as I did that there was a loud pop fron the fuse panel. Upon checking the fuse had blown, so I tried it once more with the same results. The pop was so loud you could hear it from outside the car! It almost seems like a high voltage short. So how do I fiquire out what or where the problem is without taking down all the side and ceiling trim? The fuse panel is located under the rear seat. Thanks for any help you can give me.

Is it a factory sunroof? Has there been any work done that could have possibly lead to a short? Does it have a cloth top installed on the vehicle? Often times something aftermarket has been installed and a screw is run through a wire shorting it to ground. The sunshade/sunshade anchor screws are also probable causes. I think that if you remove the overhead console, the motor and connector are accessible, disconnect the motor and see if the short goes away.
