Only one goes to head lights. I came here looking for answers and it seemed everyone had similar things to look at. Battery died one day.
Fuse located under left side of rear seat with 2-row seating under left side of center seat with 3-row seating.
On 7262003 the owner heard the motor running while the vehicle was off. My 2003 Trailblazer LT battery was getting drained overnight for a week I could not find a solution even trying the videos on youtube. You should always have some extra fuses and relays to make a replacement when its needed. We carry 315 parts in stock ready to ship.
