It's usually good to establish a relationship with your Chevy dealership, this way they'll have your maintenance and service history already and they know your vehicle's history. Often dealerships apply that diagnostic fee toward the work you're having done. I do not have access to pricing for service, and labor cost. If you would like for me to locate a Chevy dealership in your area, or research your VIN, please private message.
