    I have a 1999 Sienna with DRL that lost all headlight function (DRL, Low Beams, and High Beams). Main fuse and individual low/high beam fuses are okay.

    I just purchased a 1999 Toyota Sienna in darn near mint condition. The only problem is that the passenger sliding door has a rattle to it. It is really only noticed when I am driving in town. It rattles a little on the open highway, but not bad. It almost sounds like it is coming from the...
