Rear Sunroof Drain Routing

[alw85]

I fixed the front sunroof Friday and thought I'd had the rear one fixed by moving the drain lines upto where they were angled towards the drain behind the tail lights. To make a long story short the rear sunroof still isn't draining properly; does anyone have suggestions or know hoe the tubing should be routed? I'm considering getting some pvc pipe and some barb fittings to run between the sunroof and the drain line exit.

Is the sealant still good on the little rectangular boxes the hoses attach to? If you havn't, suggest redoing all of that.

I put fresh silicone down and found the hoses drooping causing them not to drain. Rerouted them and it's still not draining properly.

I fought this for years ended up being the seals were flipped the wrong way. Not sure who did it or if I did it at along the way.

D2 should not have rear axle height much more than front axle. These are not "kinetic design" cars. Then rear hoses will not have trouble to drain water.

Yep, but when the drains were dipping lower then the where they 90 do then they won't drain. That's the issue I ran into which is why I'm considering pex or 1/2 inch pvc

You could always add a rear drain hose on the back of the tray somehow especially if you park at a back slant.

Most sunroofs have front and rear drains. Guess the sun belt of Great Britain never has rain or they enjoy misery and dripping interiors. I'm betting on misery

Also the plastic warps on the sunroof casket. You may need to remove it and reseal it. Sometimes the water gets in under there and the tray doesn't catch it.

The drain tubes end behind the left and right rear brake lights.
