In this broadcast of Ron Ananian, The Car Doctor, Ron helps two listeners with car issues.


Dan in Connecticut has a 1996 Buick with issues related to the brake lights. The third brake light works, but the regular brake lights and hazard lights do not. Ron explains that the brake light switch is likely functioning since the third brake light works, and he suggests the turn signal switch is probably the issue. He recommends testing the turn signal switch using a wiring diagram and checks for voltage at the switch. If there's no power on the other side of the switch, it's faulty. He also suggests using a scan tool or testing the cruise control system to further confirm if the brake light switch is functioning.


Walter in Pennsylvania has a 2012 RAM with a recurring EVAP system issue. He replaced several components like the gas cap, vapor canister, and EVAP emission system, but the check engine light came back on. Ron advises Walter to properly diagnose the issue rather than replacing parts again. He talks about the importance of the system's integrity, mentioning that even a tiny leak can trigger the code. Ron suggests using a smoke machine to detect leaks or checking the rubber hose connections. If there's no leak, the problem might be with a faulty EVAP sensor.


The next call involves a truck with intermittent performance issues where it dies after driving for about an hour or two. Ron discusses various diagnostic steps such as checking fuel pressure, mass airflow sensor, vacuum readings, and electrical connections to determine the root cause. He emphasizes the importance of replicating the problem conditions rather than relying on tests when the vehicle is functioning normally, and warns against "throwing parts" at the problem without proper diagnostics.
Last call for today is about a 2006 Buick that's having trouble with its battery and charging system. The caller has replaced the alternator multiple times, but the problem persists. Ron advises the caller to perform an electrical draw test, checking for any parasitic drain from the electrical system. He explains the concept of an electrical draw test, comparing it to checking water pressure in a kitchen sink. Ron stresses the importance of ensuring the battery and connections are good, and performing tests to isolate the problem rather than relying on faulty assumptions. He concludes by highlighting the significance of proper diagnostics in solving car issues efficiently.

All calls are technical, with Ron offering advice on testing and troubleshooting specific parts using a methodical approach. He emphasizes the importance of diagnosing before replacing parts unnecessarily.
