Pure common sense .....so many shops out there lack this and then the customer pays the price. Nicely explained

Honestly God bless you sir. Thank you for the great explanation and actually understanding that not everything needs to be replaced to find the problem. Every shop I went to want to make me change everything that’s connected to the problem and most of the time it doesn’t even fix the problem and it was something as simple as a wire that was corroded.
