I pulled my hair out on this when it happened to me, I replaced the gasket, poured draino in the gutter and finally wound up taking it to the shop where they used an air gun to blow out the gutter drains. Look at the bottom of your car about 2 inches in from the door you will see what is called the pinch weld for the uni-body. This pinch weld is where the sunroof gutters drain to, 4 total, one on each corner of the sunroof. If one of these is damaged you will have to straighten it out as best you can to allow the water to drain properly. Good luck

It is extremely hard to do onything with the sun roof and keep it from leaking. TAke it to an auto trim shop where they are accustomed to working with then and guaranttee their work,
If you have a leak you can replace just the rusted section of the brake line. Any auto parts store will have what you need to do so. Ensure person performing repair performs the job properly.
To my knowledge there isn't one, but at the salvage yard we have people come in with the problem that the electric switch that operates the sunroof, doesn't work anymore, it's usually a bad motor, and not the switch itself. In dire straights, we take out the guts of the sunroof motor, so that persistant customers can manually slide the sunroof back and forth, as to whether it still locks tho, so far not yet. But check your switches and fuses before you try the no guts in the motor trick.
If it is because of the drive, it may need a flywheel also. If it keeps burning out the wiring, I would change brand of starters.
