Sunroof drains clog and leak water into the car interior on Saab 900

My 900 turbo had an issue where the sunroof drains would get clogged with leaves and other debris, causing water to leak when it rained and the interior to flood. Upon some research and talking to other owners, I learned this is pretty common with this model. Using compressed air, you can put the nozzle up to the drain and force air through the drain duct, thereby cleaning it out.
