Sunroof Rear Drain

[camino70]

I cleaned the front drains with string trimmer line. I tried to feed the line to the rear too, but I could never tell where the drain was. I then tried feeding the line up from the bottom. Even so, sitting in Atlanta traffic for an hour in torrential downpour, the sunroof began to leak down on me. I got my hands on an endoscope and fished it back a little over a foot:



I hope this helps someone, I still couldn't figure out to clean the drain. I wound up pouring a cup or two of bleach through it.

I had the same issue, I wonder if the seal shrinks?

 

[camino70]

Can I use draino for the rear drains? Or is the best solution to pull the headliner and feed the line down the drain from there?

I wouldn't use harsh chemicals like draino, definitely try to use the line method.

Thanks Harvey, I have a problem....left truck at Austin airport last weekend, rained like crazy while gone. Long story short, carpets are wet front to rear, not soaking wet more like just got shampooed wet, guessing sunroof leak. I was able to fish trim line down front drain holes about 5 feet on both sides then would go no more, pulled back trim line no sign of gunk on end. Have no clue where rears are. Does anyone have a diagram where fronts and rears exit? I want to tackle this from the bottom up. Thanks in advance for your help.

if its wet front to back I would say you have more than the Sun roof leaking.

Try a can of Coke. Pour that down the drain, let it sit, then flush with clean water.

Good idea! I'd use Diet Coke, though. Our trucks are fat enough.

Actually, I'd use Diet because I don't want to deal with the sticky sugar in regular Coke.

Thats why you rinse with clean water, I do not know if the acidity between the two is different or not, for my money I'm going top shelf and not going diet. Lol

Ill try the coke this weekend and report back. Thanks.

@ScubaJon, care to elaborate? Thanks.

I would close all the windows turn on ac/heat fan full blast in the recalculate mode. close all the doors. Spray a mix of dish soap and water around all the windows and 3rd brake light and the feet of the roof rack might even do the door seals. If you see bubbles you have found the leaks.

I cant see how the sunroof would get the carpet in the back of the car wet. You got water getting in some where else.

My sunroof seal had a small hair crack, it was not leaking enough water for me to install a new seal but it was sweating. I painted the whole seal with plastic dip. Problem solved.

Thanks for all of the tips, all drains work fine, was able to fish trimmer line in fronts, tried rears from bottom up to no avail. Used soapy water on all seals, windows and roof rack, no bubbles. Weird, I'll keep an eye on this.
