lexus082 Posted October 7, 2006 Share Posted October 7, 2006 I am not sure where the leak is coming from. I first noticed it a few days ago when it was raining and also windy. I was at a traffic light and water started to drip of the button for the map light. I was sort of shocked to see the water dripping onto the seat. I think it coming from the sunroof. Could there even be anyother way for water to drip off of the map light button? Quote Link to comment Share on other sites More sharing options...
lenore Posted October 7, 2006 Share Posted October 7, 2006 The drain lines for the sunroof may be clogged. there are usually 4 two to the rear and two to the front. Finding them is the trick. Usually there is plastic tubing going through the trunk from the pillars on the rear windows. They usually exit in the wheel well. Ask Lexus where they are located, sometimes running compressed air from the bottom up will clear them, or they may be pinched somewhere.

anthonyiez Posted October 7, 2006 Share Posted October 7, 2006 like lenore said i bet the drains are clogged, but imo the most likely place is right at the sunroof. typically leaves and other matter clogs the holes so the water can't drain out. use your hands to clean out the bulk of it, because you don't want to blow too much debris down the lines. i should add this is the most common water leak on all cars with factory installed sunroofs.

lenore Posted October 7, 2006 Share Posted October 7, 2006 check the drain holes on top, and use a vacuum cleaner when you find them, The holes go to tubing that routes to the bottom of the car. I would not force the stuff down. Quote Link to comment Share on other sites More sharing options...

SKperformance Posted October 8, 2006 Share Posted October 8, 2006 Use PB blaster and spray tech track edges which will allow it to drain to the rear corners which you cannot see. Then spray it into the front corners directly and watch it flow out by you door jams on the ground. Quote Link to comment Share on other sites More sharing options...
lexus082 Posted October 11, 2006 Author Share Posted October 11, 2006 I'm glad I asked, I didn't think anyone would respond with such reassuring advice. Thanks. I will post my findings. Never knew the sunroof had drains that went to the rear of the car. I'm glad I asked, I didn't think anyone would respond with such reassuring advice. Thanks. I will post my findings.

lexus082 Posted October 17, 2006 Author Share Posted October 17, 2006 **Just used PB blaster to clean them up. I saw four puddles from each drain so hopefully all is good now. I think the right front drain was a little backed up it took longer for the pb blaster to stay down in the drain hole at first. Quote Link to comment Share on other sites More sharing options...

lenore Posted October 18, 2006 Share Posted October 18, 2006 Ok SK, I have never used or seen PB Blaster, what exactly is this compound? Quote Link to comment Share on other sites More sharing options...
lexus082 Posted October 19, 2006 Author Share Posted October 19, 2006 Its made to dissolve rust from rusted bolts I believe. It penetrates through rusts to assist in loosening rusted bolts/nuts. Quote Link to comment Share on other sites More sharing options...
SKperformance Posted October 19, 2006 Share Posted October 19, 2006 It looks like this. http://www.pbblaster.com It is available in almost every hardware auto type store. It is about $5 and is easy to find if you need more info from Google. I prefer to use it over other things as it has no pressure and is passive in application. It also has a catalyst action to bubble up and clear a clog. Quote Link to comment Share on other sites More sharing options...
lexus082 Posted October 20, 2006 Author Share Posted October 20, 2006 Smart man. Thanks, SK. **Update: Its rained a few times since I have completed the opening of the drains and no leaks so far. Home depot also sells PB blaster, I saw it there yesterday. Quote Link to comment Share on other sites More sharing options...
Stretchp2 Posted April 6, 2014 Share Posted April 6, 2014 This is usually the culprit! I'm gonna clean the hole out today. Tried the straw method now Pb blaster time. Quote Link to comment Share on other sites More sharing options...
