Ron Ananian, The Car Doctor - June 27, 2026 - Hour 2 - How Many Parts Can You NOT Replace?

This week Ron explains why great technicians don't start by replacing parts—they start by proving what's actually wrong.

A stubborn Honda Accord air conditioning problem, a Ford Edge with two unrelated faults, and a discussion of real-world diagnostic strategy all reinforce one lesson: understanding how a system works will always beat guessing.

Also this hour:

• Why testing beats replacing.
• Ford Edge A/C diagnosis after collision repairs.
• Battery failures that don't behave like battery failures.
• Maintenance advice for a high-mileage Ford F-150.
• Chrysler cruise control problems.
• Why today's technicians must understand how modern vehicle systems communicate.

As Ron says:

"The challenge isn't how many parts you can replace. It's how many parts you can NOT replace and still fix the vehicle."
