Question about 2008 Toyota Highlander
2008 highlander sunroof drain goes into the footwell but does not exit and builds up till overflows into passenger side. How do you access the footwell to clear blockage? Hose into the footwell is clear. Just need to clear from footwell to outside.
Go under car with a wire and poke upward. Try to pull out as much blockage as possible so it won't happen again. You can make a small bend in wire end to do this. GOOD LUCK FRIEND.

There are 4 drains on the sunroof (2 in each front corner, 2 in each rear corner).
If you want to check to see if they are clear, you can do this.
Get a squeeze bulb (about the size of a turkey baster) and squirt water down each drain, look for water draining out at the bottom of the car. For the rear drains, park the car on a slight uphill, and gently squeeze water down the drain trough on each side, here again, look for water draining out of the car.
If those ar clear, next step is to check the seal of the glass. The drains are only designed to take in a small amount of water, if there is too big of a gap between the panel and the body, it will over run the drain troughs (kind of like when the gutters on a house get stuff in them).
Finding water leaks is kind of a pain, but not if you take it a step at a time.
One thing to remember, water does not run uphill.
So to further water test it. Find a place where you can park it uphill or downhill, grab a flashlight, a friend and a hose.
Start at a low spot, and work your way around the sunroof (one person inside with the light, one outside with the hose). Just let the water run slowly, you don't want to use a nozzle or a spray.
Once you can see when the water starts leaking on the inside, you can narrow down the cause.

You need to open the sunroof fully and locate the small drain holes at each corner. They will be blocked with debris. Get a piece of welding wire or the likes and carefully unblock the hose by prodding and pouring water down it. When cleared the water shout run away freely.

never worked on a hummer but rule of the day is that there always is a drain on the firewall on the engine side. usually a small rubber hose about two inches long direced downward. Usually you can stick your finger in there and clear it out. Don't shove anything hard into it or you can punch a hole in the evaporator core.
