Chevrolet Trailblazer Relay Parts Questions & Experts Answers
Q: What is the purpose of relays in Chevrolet Trailblazer and Buick Rainier's electrical system?
A: Several electrical accessories in a vehicle, such as the fuel injection system, Horns, starter, and fog lamps, use relays to transmit the electrical signal to the component. Relays have a control circuit and a power circuit, with the control circuit opening and closing the power circuit. If a relay is defective, the component will not function. Most are found in the engine compartment or fuse boxes. To test, remove and check it for continuity using an ohmmeter. The terminals of ISO relays are numbered to indicate their circuit connections and functions.
