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."
