Automotive Diagnostic Podcast

This week on the show I share my thoughts as we wrap 2025, and look forward to the next year. Last year this time I recorded an episode on goal setting, and know I have a whole year of data to look back on to see what went right, what went wrong, and how to adjust for the future.  Website- https://autodiagpodcast.com/ Facebook Group- https://www.facebook.com/groups/223994012068320/ YouTube- https:...

Both had pre-existing issues that presented no issues to the customer, but presented major obstacles for us when attempting to program...

Today on the show I share a thought process that I've been adding into my diagnostic decision making. We weigh the value of any test method we perform- How much time/effort/cost does a test require? How much does it tell me/how many things does it eliminate? When faced with a time consuming, difficult, (and often intermittent) diagnostic challenge, should we consider that a part replacement i...

This week on the show I share a case study on a 2017 Chevrolet Malibu. Not charging, no power steering, idle surging, stalling at idle, no heated seats or rear defrost...

We often deal with strange control module issues- codes, warning lights, communication faults, or reduced functions. While the causes are numerous for each individual situation, one thing that may "fix" the issue is a battery disconnect or capacitive discharge. I'll share 3 vehicles today where a CAP discharge was the fix for strange problems.  Website- https://autodiagpodcast.com/...
