There are many out there including myself that have had the misfortune of wet carpets and drowned out rockers due to blocked sunroof pan drains and or blocked slit drains in the rocker cavity. Unfortunately for what ever reason Toyota decided to let the spill over water along with whatever debris to empty into the rocker cavity leading to soaked carpets and more importantly the malignant creep of rust. I have devised a way for the sunroof to drain to the outside of the vehicle instead of the rocker by extending the drain tube and having it exit through the first drain plug in the rocker.
1- Remove the inside molding/kick panel from the PS and DS and the first drain plugs on both sides.
2- Pull out the black vinyl hoses inside the body cavity they are behind the wires that are stuffed in there. NOTE use some work gloves I cut my finger on some of the sharp edges inside that cavity, also DO NOT pull down hard on the drain tube if it pops off the sunroof pan shame on you!
3- I used a hard 1/8 plastic water line to snake from the drain plug to the opening in the kick panel to use as a guide to push the the drain tube extension on. When the guide is snaked up from the bottom it will be in the small space next to the door hinge not the space where the tube normally drains I tried but was unsuccessfully.
4- I purchased some black vinyl hose from Home Depot with a an outside diameter of 5/8 and an inside diameter of 1/2 which slips perfectly into the existing drain tube.
5- The 5/8 hose fits snugly in the round rocker drain hole, I used lots of dish soap to help it along the way. Its a bit tricky it helps to pull the guide while pushing the new tube from the bottom.
6- When you have the new tube extending from the rocker drain to the kick panel opening you are going to glue them together with PVC cement make sure both tubes are cleaned with PVC primer. Push the the 5/8 hose into the existing drain as far as you can and inch or two will be fine.
7- After the cement has cured you are going to pull the slack out of the tube so its straight and not kinked.
Some tips:
Use plenty of soap while pulling the tube back down and it helps to push it from the top at the same time. If it gets stuck push it back up and add more soap don't keep pulling.
Make sure that the tube is in the corner of the of the body cavity towards the outside of the body because its wider, you can feel it with your finger. The DS pulls down easier then the PS
8- After the hose is straight you can trim the excess off leaving a few inches extending down.
You are done! If your drain tubes get clogged you can simply push some string trimmer line completely through them to dislodged and debris. I would not block up the rocker drain slits but make sure they are unclogged to let any condensation drain through them. I'm going to spray some Eastwood Rust Encapsulator inside the rocker the best I can followed up with some of their Anti-Rust spray.
