Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Greetings and welcome to Just Answer, Your complete satisfaction, a positive experience and a resolved issue is my goal for you.According to the schematic the C4500 is a fuse and not a circuit breaker. Did you verify the fuse has power to it with a test light or how did you check it?If the relay does not have power on any of the 4 holes then either there is an open from the fuse to the relay or the fuse is blown.I will include a schematic to reference, keep me posted. Thanks.
