Where is the water sloshing around in the rear window area of your Honda Del Sol and how can you get it to drain away?
I had this problem recently - I solved it by removing the interior of the car (just the rear plasitcs & speakers) and then unbolting the rear windo assembly - this exposed the… area where the plugged drain holes were - after cleaning the gunk out of the drains - I resealed the window assembly in place with some silicone sealant, and replaced the interior plastics - took about 2 hours in my front driveway, working at an unhurried pace. ANOTHER OPTION: Before you remove the rear window , try first popping out the 'drain plugs' . there 's one on each side underneath the car on the rear portion of the side skirts. You might have to remove a couple 'plastic' screws on your side skirts. The plugs to the drain are covered by the skirts. I was able to remove the 1st (2) plastic screws on each side skirt and feel for a plastic drain plug. I just popped mine out and a bunch of water came out. I just left em out so the water can drain full-time. That emptied out the drain tube which is behind your rear window. If that doesn't work, THEN , attempt to remove the rear window assembly and that will expose a black drainage tube . (MORE)
