Ron Ananian, The Car Doctor - April 26, 2025 - Hour 2 - Tricky Electrical Problem on a 13 Suburban - (855)560-9900 24/7 Hotline
🎙️ Ron Ananian: The Car Doctor — Episode Recap Main Topic: The True Cost of Diagnosis & What It Really Takes to Fix Modern VehiclesSpecial Note: Catch Ron on WOR Radio (NY) at 9:40 AM, Monday, May 5 to kick off a special series on Dashboard Warning Lights — starting with the infamous Check Engine Light. 🔧 This Week’s Opening Rant: Diagnosis Costs Are No Joke Ron opens the show addressing a hot topic: “Why are diagnosis costs so high — and why are people so shocked?” With today’s vehicles functioning more like rolling computers, diagnosis isn’t a matter of swapping a part or running a quick test. It requires training, tools, and time. As Ron says: “Have we taken things to an extreme? Maybe. But this is where we are.” 📢 Coming Next Week: Jared Wilson & the Fight for the Right to Repair Ron previews an upcoming conversation with Jared Wilson, a farmer-turned-activist who’s become a key voice in the Right to Repair movement. Jared made national headlines fighting for access to repair his $600,000 farm tractor. When it broke mid-harvest, the only option was to tow it to a dealer — risking total crop loss. Ron highlights how this battle affects everyone — including the food on your table. 📞 Caller Spotlight: Eric in PA — 2013 Chevy Suburban Eric shares a bizarre issue with his Suburban: After a GM crate engine swap, the voltage drops while driving. The A/C shuts off, and the truck goes into limp mode. The fix? Turning on the headlights restores the voltage to 14V. Ron’s take: This could be tied to GM’s energy-saving mode, a headlight circuit anomaly, or even a network module failure. Suggests digging into: Scan tool data: Are any modules dropping offline? Wiring harness & cluster connections The oil pressure sensor, which might be feeding bad data to the instrument cluster. Rule out any aftermarket electronics or engine swap side effects. Ron’s philosophy: “Tell me what’s good. Before we chase ghosts, let’s confirm what’s working.” 📞 Caller: Joe in NJ — 2003 Malibu with Low Miles Joe scored an '03 Malibu with only 66k miles but had to replace the water pump.Ron says that’s not shocking for a 22-year-old vehicle. Key tips: Test coolant for acidity using litmus strips (basic chemistry flashback!). Perform a coolant flush using a machine, not just a drain-and-fill. Stick with DEX-COOL (modern versions have resolved early issues). Brands like PEAK are a good choice. 📧 Listener Email: Bob in SC — 1996 Ford F-150 Transmission Bob’s E4OD reman transmission: Intermittently slams into reverse, loses all gears, and sometimes resets by cycling the key. Ron suspects a possible control or electrical issue, but with a nearly 30-year-old truck, it's also about parts availability. Advice: Consider another reman while parts are still available. Or bench it and inspect — especially if this isn’t your only vehicle. 🧠 Ron’s Final Thought: “You’re not driving a car — you’re driving a computer on four wheels.”Diagnostics today are about interpreting networks, modules, and signals, not just checking spark and fuel.
