Angry Roof Drains

I have 2010 Equinox with sunroof. Heavy leakage on back seat floor. Had roof drains cleared out by dealer and put sealing tape around sunroof. STILL leaking, I'd like to know how? and anything I can do to prevent. Also have heavy inside condensation on windshield. Have to do something as my nephew who lives with me has asthma and this is aggravating it. Any help appreciated. Theresa

Are you sure that you don't have a leaking heater core. That would produce condensation of the inside of the windshield when running the defroster. You can usually notice the sweet smell of antifreeze.

If its like the VUE was...there are 4 roof drain hoses coming from the sunroof 2 in front and 2 in back. I'd bet one of the hoses going towards the rear and down the B pillar popped off - especially if the dealer used compressed air to clear it. Those sunroofs aren't designed to be water tight...hence the drains.

Is your headliner wet at all anywhere?

Since they're both thetas and bodies are almost identical, I can pull out the FSM from the Vue if you want to know exact location and how to get to it. Just let me know.

Every sunroof that I have ever worked on, or looked at the diagram, had the rear drain lines go down the C pillar.

Not that it matters but the Vue FSM says the hose runs down the B pillar... just checked...Pretty sure it's the same sunroof in any of the thetas of that vintage.

Either way I'm thinking the place to start looking is the rear drains. Unfortunately the headliner has to come down to see them.

Thanks for the info.


On dropping the headliner...it would be nice if you could drop a mini inspection camera down the hose, and avoid taking down the headliner. But, i guess the headliner would have to come down to fix it anyways. Possibly OP can find leaves or some blockage in the S/R pan and just scoop it out.

That would make it pretty easy...Its really rare that the rear drains on these are the issue...99% of the time its the front ones which are much easier to get to since you only have the drop the headliner a little bit by the front door and take off the some trim pieces to get to them - ask me how I know...LOL

I'm wondering if its even possible that the rear hose in that area is cracked or out of place so the water isn't making it all the way to the outside. Like you said - headliner has to come down anyway unfortunately.
