Are there any easy ways to unclog my sun roof drains without having to tear stuff apart??

 

Try some compressed air. No, I'm not talking about the cans used to clean keyboards. I'm talking about using an actual air compressor.

 

Yeah if you took it somewhere they'd shoot maybe a little brake clean to try to break it up a little in the tube and follow it with sticking an air nozzle in there to blast it out. You don't want to leave them clogged up as the underside of 4th gen sunroofs aren't painted and only speeds up the rusting out problem they get.

 

compressed air is the way to go. I had water leaking into my back seats and found out the rear drains for the sun roof was clogged. i stuck a long piece of metal through it then ran the compressed air pushing all the crap out the other end of the tube found some where in the trunk's corners.
