Sunroof is leaking water into vehicle on 2001 Toyota Sequoia

My sunroof is leaking water into the interior of the vehicle. I have located the front drain holes and drain tubes, and they are clear. The dealer wants to take the inside of the car apart for big money. What might be causing this problem and what is the most cost effective solution for fixing it.

Are you certain it is the sunroof leaking? Or could it be the windshield seal? If it is the sunroof indeed, the headliner likely has to be dropped to see if there is a drain tube that is disconnected in line to the outside of the vehicle. They are probably thinking of a liberal amount of "actual time" in quoting the continued diagnosis and hopeful repair. Tough situation to be in. You could always get a second opinion from another shop. Here is a link to some other shops near you. Worth a call. Good luck. http://repairpal.com/directory?address=97470&car_brand_names=Toyota

I have an '01 with the same problem. I gutted the interior looking for a bad drain tube but found nothing. It seems that the water doesn't drip into the channels as it should but onto the headliner. When it rains I can see it dripping from the metal framework channel that is part of the glass onto the headliner. Not sure how to fix it but tearing the interior apart won't help. It has to do with the molding and sealant used on the glass.

I thought mine (2002 Toyota sequoia) leaked too, so I checked the sunroof after a rain storm... it was dry. The Toyota had still taken on water. It turns out that the metal around the windshield rusted out and water was leaking in through the rust. You might want to have yours checked. good luck
