The turn signal fuse in your 2002 Chevy Express 1500 van may keep blowing due to a short circuit in the wiring, a faulty turn signal switch, or a malfunctioning component in the turn signal or lighting system. Corroded connections or damaged wiring can create excess resistance, leading to a blown fuse. It's also possible that there are issues with the trailer wiring harness if equipped, which can cause similar problems. Inspecting the wiring and components for damage or wear can help identify the root cause.
