#1 of 6 Water leaks inside car by bobdp1 Jun 13, 2008 (5:14 pm)
My 2006 Avalon Ltd has been in shop for 3+ weeks for water leak. Second time water has gotten into car. 1st time was a cracked cowl at windshield, took 3 trips back to get the moldy, smelly carpet replaced. this time the leak is from a disconnected hose at sunroof that let water under carpet behind driver. Toyota is replacing carpet again, cleaned interior metal surfaces with bleach to get rid of mold, and replaced all seat foam. I am worried that once the warranty is up I will continue to have water leaks. Anyone else having water filtration in cabin? And don't get me going on the worthless nav system, for 2500 bucks it doesn't reliably take you anywhere. Replies to this message: rpfingsten (Jun 13, 2008 11:23 pm) bobdp1 (Jun 14, 2008 6:54 am)

Replying to: bobdp1 (Jun 13, 2008 5:14 pm) bobdp1...      I have an 07 avy xls and about 3 months after I bought it I ran into a water leak.. My car was parked in a parking lot during a down pour.. when i got in the car I noticed a little water on the dash.. thought it must have been something I "splashed" in in my haste to get into the car and out of the rain.. but when I started to drive the car, I noticed water coming out of the speakers on both A pillars..... couldn't believeit... took it straight back to the dealer.. turns out drain tubes on the sunroof were not "hooked up".... they hooked em up and havent had a problelm since..   Roland Replies to this message: bobdp1 (Jun 14, 2008 6:54 am)

#4 of 6 Avalon sun roof leak by tim93 Jul 23, 2008 (9:34 am)
I just ran across this problem on our car.Believe it or not this is a easy fix if you have some mechanical skills.What I believed happened is when the factory installed the rubber drain hoses to the drain outlet on the sunroof they did'nt factor in that the hose might shrink during heating and cooling of the car and the hose pulled away from the drain the same amount on both sides.To fix:disconect battery,waite 10 minutes,open sunroof and remove the inside molding around headliner,should pull right off,pull down the hand grab handle and pry off the cover caps carefully to expose the mounting clips,with a screwdriver or needle nose pliers squeeze the clip and pull handle off,then remove the plastic cover on the sunvisor pivot to expose two phillips screws to remove the sunvisor,you don't have to completetly remove it,let it hang,next the side pilar cover has to be taken down,there is a rubber molding and one clip holding it up,pull the molding back enough to reveal the cover,pull it out enough to get to the clip,I took a pair of needle nose pliers and twisted the clip to get it out,set the cover on the dash,this should give you enough room to pull the headliner down(front corners of sunroof) to see the end of the hose,pull the hose toward the drain and slip it over the drain fitting,take a wire tie and put it over the hose so this will not happen again,reverse taredown prosedure,do other side same way and you're good to go,,,hope this helps.
#5 of 6 2000 Avalon water leaking inside by toyavalon2000 Apr 26, 2009 (11:40 am)
2000 avalon xl with xls features with moon roof leaks at front door where the seam is at the frame and wets floor and carpet. Some people think call it the a frame. The moon roof does not have any internal drains that i can find. I can't find and specs or images of moon roof layout. When closed water runs down the front windsshield side. So is it leaking inside of moon roof frame or is the windshield leaking.   I just found this. So moon roof or windshield?   Component Description: 34. STRUCTURE:BODY Bulletin Number: BO03100 Bulletin Date: NOV 2000    Vehicle: 2000 Toyota Avalon Summary: PRODUCTION IMPROVEMENTS HAVE BEEN MADE TO MINIMIZE THE GAP BETWEEN ROOF BODY PANELS. A FIELD FIX IS AVAILABLE FOR INSTANCES WHERE THE SEALER UNDER THE ROOF MOLDING MAY BE INCOMPLETE ALLOWING WATER TO ENTER THE VEHICLE. ( NHTSA ITEM NUMBER - 616099 )    And what is the best fix?

Replying to: toyavalon2000 (Apr 26, 2009 11:40 am) My car leaked on the left side and next the right side so i think it's clogged. I called the dealership it's a about 250.00 to take it apart and clean it. Way too much. OK i find these 2. On another forum a guy said use a air pump to see it it clears and another a guitar string to auger it out. So if anyone else has a problem hopefully they can fix it.   http://www.toyotanation.com/forum/showthread.php?t=270195   http://www.corrado-club.com/faq/detail_faq.CFM?FAQID=144   I'll try it tomorrow and let y'all know how it goes. Good Luck to ALL!
