My 2005 TB LS EXT suddenly has what I think is an electrical short somewhere. Both low-beams and forward running lights stopped working. No daytime lights at all. I can only drive at night using high-beams (which aren't affected). Also, battery is inexplicably draining in 2 or 3 days to a dead battery. When I jump-start the battery, it holds a charge just fine; but, if I don't drive for a couple of days, the battery is drained. That's a short, ain't it? My first suspicion is any electrical wiring near the exhaust manifold (melted insulation). But the real question is if this specific electrical problem is a known 2005 TB problem.
