Body - Power Sliding Door Re-Opens Before Fully Closing

If the power sliding door on a '05 Odyssey starts opening again just before it flilly closes, the upper roller could be binding. This can happen if the upper rail is too narrow where it curves toward the body. The inside width of the upper rail should be 20 mm + 0.3 mm.

To check if this is the problem, close the door by hand, and note if the upper roller binds where the rail curves in. If it does, use a block of wood and a hammer to spread the rail sides apart in that spot. Be really careful when you do this so you don't damage the paint. And don't spread the rail sides too far apart, or the door will rattle.
