Hello friends. I just joined the forum. I bought my daughter a 2010 Prius a couple years ago, has 170k or so miles now. I'd like to clean the sunroof drains. I see where the openings are in the front plastic pan. I put water in the pan and I see water draining out the tiny openings in the bottom of the frame beneath the doors. One side drains slowly, and I can't poke anything through either side to clear the line. I own a couple other Toyota and Lexus products with sunroofs, and they have round openings of a good size, several mm diameter. You can easily push through a cable, brush, etc. and clean crap out of there. I tried a very small diameter bike derailleur cable on the prius and is only goes in a couple inches before it hits a hard stop. I was not able to get anything in from the other end of the line either. Does anybody have a method for clearing these drain lines? I'd rather not used compressed air for fear the 13 year old plastic tubing will come off fittings under pressure.
Well you don't want a blast 150 PSI through there All you need is about 8 to 10 PSI so you turn your regulator way down while squeezing the handle on your air delivery gun and you set the regulator around 10:00 12:00 PSI that shouldn't hurt to drains If you can get to the drain down at the bottom of the car the rocker panel put a rag up at the top or a person up at the top holding a rag and blow backwards so you're blowing the trash the wrong way the way it went in it'll usually go back better than trying to push it through sometimes you have to do your toilet the same way That's why there's a clean out might be something to look into I have done this on many other Toyota's over the years cleaning the sunroof drains older Toyotas had them in the front and the back of the sunroof corners.
