Yes, that’s possible. Generally however the best way to interact w/a mechanic is to ask them to solve the specific problem you have, rather than direct them how to do it. The more clarity you can provide about what exactly the problem is, what all the symptoms are, under what conditions these symptoms occur, the better you provide that information to the mechanic, the quicker will be the solution. I used to write it all down and tape that sheet of paper to the steering wheel when I took the car to the shop. Tell them the best you can what the problem is and otherwise don’t tie their hands behind their back, just let them use their professional expertise to solve it. If a shop can’t figure this one out, find another shop. Ask your friends, coworkers etc who they use for car problems.
