Not one, two, or three, but four worn/faulty door lock actuator motors! What are the odds… Slim-to-none, right?
Join Motor Age Technical Editor, Brandon Steckler and good buddy, Michael Guenther (owner of Downtown Auto Service in Crofton, NE) as they discuss a strange power door lock concern on a 2009 Chevrolet Impala.
Michael is no novice when it comes to diagnostics. In fact, he has been featured in the pages of Motor Age Magazine’s February 2024 issue. Logic and past experiences would lead most techs to hunt feverishly for an underlying fault in the vehicle’s electrical system. But, using a Snap-on Zues digital storage oscilloscope and amp probe, what Michael discovered was not expected at all.
Listen in on the conversation in this episode of Wrench Tales as Michael and Brandon work together to discuss their diagnostic approach. Learn how they used logic to determine which tests to perform, in what order, and where on the vehicle to conduct the testing that (if the customer had chosen to pursue) would’ve led to a nearly $2000 repair!
