Ron Ananian, The Car Doctor - Hour 1 - September 5, 2026

A 2020 GMC Denali arrives at R\A Automotive on a tow truck with an intermittent no-crank—and a history that would make any mechanic stop and think. Nearly three years, five different shops, multiple starters, and the same problem keeps coming back.

Ron starts where every diagnosis should start: at the beginning. Working with GM expert Ernesto through the OPUS IVS diagnostic platform, Ron separates clues from conclusions, uses factory service information and pattern-failure knowledge, and begins proving what the problem ISN’T. The trail eventually leads to a loaded voltage-drop test, a questionable negative battery cable, and a starter-solenoid connection that has seen its share of previous repairs.

It’s a real-world lesson in why replacing parts isn’t the same as diagnosing a car—and why sometimes the most valuable question a technician can ask is: What have I proved right, and what have I proved wrong?

Also this hour: when should you get a wheel alignment, why a car can be out of alignment without pulling, an A/C system that cools until the Florida heat arrives, and why guessing at refrigerant charge can create more problems than it solves.

Real calls. Real cars. Real diagnostics. Ron Ananian, The Car Doctor.
