2003trailblazer head light bulb replace
Drivers side: Gotta stick your hand way in there in front of the battery, and take the rubber dust boot off, just slides right off. Twist the bulb out, and disconnect from connector.
Passenger side: easiest if you just remove the air cleaner box, 3 screws, one on the top, one on the right side, and one on the bottom left. Remove these screws, then pull box straight up. You'll then have complete easy access to the rubber dust boot and bulb.
