Where is the rear window defogger fuse on a 2004 trailblazer LS?

The rear window defogger fuse location in a 2004 Chevy Trailblazer LS isn't standardized across all trims and builds. It's not typically in the underhood fuse box. Instead, it's usually found in the interior fuse box, often located under the dash on the driver's side.

To find it:

1. Consult your owner's manual: This is the most reliable source. The manual will have a diagram showing the fuse box layout and identifying which fuse is for the rear defroster.

2. Look for a fuse box diagram inside the fuse box lid: The lid itself often has a diagram printed on it that shows which fuse controls what. Look for a legend indicating the rear defroster or rear window defogger. The amperage rating might also be listed (usually 20-30 amps).

3. If you can't find it in the fuse box lid: Look for a diagram inside the owner's manual.

Without your owner's manual, it's impossible to give a precise location. You'll have to locate the interior fuse box and use the diagram provided there.
