Ron starts this episode talking about the value in following a diagnostic routine on a  consistent basis to diagnose and fix a vehicle. He recounts a car from the shop this week as an example; a 2016 Mini Cooper with a rear wiper problem. Then he takes a call on an 2007 Mustang GT500 where the cruise control is not working. Ron then talk to a listener that has a whistling  2011 Jeep Wrangler Sport, even if the car is not moving. In the news this week Ron covers a story of a possible power emergency in the Texas electrical grid and how it could be related to the EV world. He closes out this hour answering an email on a 2004 Chrysler PT Cruiser and a question on changing the timing belt and also discusses a recent tech tip from the ALLDATA technical library where a 2018 Ford F150 goes into limp mode due to a computer network problem and what steps need to be take to diagnose it.
