| Description of the problem | I have a 2004 toyota sienna that has a large amount of condensation inside of the passenger side headlight assembly. I first noticed it in december when the condensation froze and considerably blocked the headlight beam. When researching on the internet to find out how to take the lens off to dry the condensation i discovered that the beam assembly does not come apart and that many other owner's of the same model are having the same problem. In addition, this problem always seems to be reported on the passenger side. Eventually the condensation will cause the light to fail. Toyota redesigned the sienna in 2004 and the new, bigger headlights were a major change. The condensation slightly affects the headlights in the warmer months but is a significant problem when the temperatures are below freezing. This seems to be a design flaw affecting vehicle safety that toyota should be required to fix. |
