I've searched and havent found much. The back floorboards are soaked and I've already used weed wacker line to clear the front drains. I want to use the weed wacker line going from the bottom -> up on the rears but I can't find where they exit the vehicle.. Anyone have any pics?

 

Sunroof on my 90 Ext cab drained into the rocker panel behind door.
Can't get to it from the outside. I had to remove the large plastic panel begins the door to access it.

 

Yea I got the rear plastic off partly enough for me to get to the drain. I blew it out with an air compressor and it seemed clear. Need to figure out why my sunroof isnt draining properly and not sure what else it could be.

 

Make sure if using compressed air to only use as little pressure as possible. I have a friend who constantly fixes people's sunroof drain tubes after they "fixed" it with compressed air. A long pipe cleaner/trimmer line is always better than compressed air. Since they are designed to drain water away by gravity (ie not pressurized). If you have a complete blockage and hit it with compressed air you can separate you drain tube at a joint. Then you have a small project. Just a word of caution

 

Test the sunroof drains by pouring in water. Do they actually drain and does the water come out the end of the hoses?
If the drains are working you might have another problem. Weather stripping around sunroof seal?
