    Hey guys lookin for the DRL fuse in a 04 chevy trail blazer. A buddy of mine is wanting to hook a headlight flasher to the high beams as he is on a local FD but the flasher we have wont work unless the DRL fuse is pulled. And rather go out and get a new flasher for cars with DRLs this would be easier. Plus even if I did have a DRL flasher I would still need to find the fuse to hook the flasher to so anyone with a answer to this, it would help out alot. Thanks

    Check the under hood fuse panel for a fuse marked "HDM" (Location #53 15 amp). It may or may not have it as there's an early and late production '04. If the fuse isn't there check for a relay marked "HDM" in the same panel and pull this relay.

    NOTE: Due to the wiring revisions to the DRL's on the TB's/Envoys in '04...pulling the HDM relay may also disable the regular headlights.

    Accually found out today that it is a 05 trailblazer, so if it makes a difference I am not sure but...

    Ok, mid '04-up should have the HDM fuse. But it still may affect the normal head lights operation. Just depends on the original vehicle destination. Won't hurt anything to pull the fuse to try them either way.
