Ron Ananian The Car Doctor™Ron Ananian, The Car Doctor -June 27, 2026 - Hour 1 - No Codes. No Clues. Just Good Diagnostics.
A late-model Ford Edge had everyone stumped. Multiple repair shops, multiple replacement parts, no check engine light, and no diagnostic trouble codes—yet it still refused to start.
Ron explains why the best diagnostics begin before the engine is ever cranked, using live scan tool data like coolant temperature, ambient air temperature, battery voltage, fuel pressure, and barometric pressure to verify what the PCM believes is happening. It's a lesson in real-world troubleshooting that every technician—and every vehicle owner—can appreciate.
Also this hour:
- A discussion on complete automatic transmission fluid exchange procedures.
- A Hyundai Palisade with excessive oil consumption and what owners should expect from the manufacturer.
- A Kia Sportage with stubborn brake bleeding issues after multiple hydraulic repairs.
- Why diagnostics should always begin by identifying what's working correctly before chasing what's broken.
As Ron reminds listeners:
"Tell me what's good... and I'll tell you what's bad."

Ron Ananian, The Car Doctor - Classic Car Doctor, October 17, 2015 Hour 1 - Two Repairs That Made Me Shake My HeadRon starts the hour with not one, but two Repair of the Week stories that left even him shaking his head. Sometimes the hardest part of fixing cars isn't the diagnosis—it's understanding how they got into that condition in the first place. Ron then takes a call on a 2004 Pontiac Vibe and answers a variety of maintenance and repair questions before welcoming special guest Jerry Ostalecki from GetGibbs.com to discuss lubricants, corrosion protection, and keeping equipment running longer. Later, a listener with a 2007 Toyota Matrix calls after removing and reinstalling a factory CD player only to find it no longer works, leading to a discussion about electronics, wiring, and the surprises that can occur when taking modern vehicles apart. Ron also answers an email regarding a software issue on a Ford F-150 and explains why today's vehicles often require as much computer knowledge as mechanical skill. All that and more this week on Ron Ananian, The Car Doctor.
