It is possible to talk to a mechanic for free, though the services provided for free vary between auto repair specialists. Free services are typically limited to checks and inspections.
Pep Boys, for example, offers a free battery test, code retrieval, brake inspection, windshield wiper installation and alignment check. Goodyear Auto Service offers a 29-point auto inspection that includes a complete check of the tires, fluid levels, braking system, alignment and suspension. Goodyear also examines smaller, easily replaceable parts such as filters, headlights, bulbs and belts. Discount Tire offers to repair any flat tire for free as long as the tire is not damaged to the point of needing to be replaced.
