I’ve been both…. technician…and service writer (manager).
The service writer SHOULD be a good listener. He should let the customer describe their complaint WITHOUT trying to diagnose the problem himself. He should accurately describe the customers’ complaint in the service-request….and let the TECHNICIAN diagnose the problem and propose a fix/repair.
It was my experience as BOTH… that when a service writer takes it upon himself to decide what the issue is…. that the next error made is for the service writer to decide the solution. I.E. “TUne up”..
Then…when the tuneup is done and the customer takes the vehicle home and the problem persists…. guess who gets the blame? (I’m thinking now of the time this exact problem occurred and I performed the complete tuneup…. valves adjusted, timing set, spark plugs replaced, filters changed, etc.…. when the real problem was that the car would not start first-thing in the morning …but would start and run just fine later in the day.
I was fired over this issue when I argued with the svc-mgr that the svc-writer was the cause of the unhappy customer. (The problem was a cracked ignition coil that would make contact/complete the secondary circuit when the temps rose later in the day…but which would not in the cold morning.)
The svc-writer was the mg’rs protege’. I just happened to pack up my tools and go to work at another dealership that very same afternoon…and by chance….the unhappy customer brought the car to the second dealer the next week. I couldn’t BELIEVE IT when I recognized the car.
The second dealerships’ svc-writer simply wrote it up as “hard to start” and further described the problem disappeared in the afternoons.
A-Ha! I sprayed freon on the coil and it failed to spark…but a heat-gun on it and it fired just as it should! Replaced the coil and problem solved. The customer is who told my new employer that I’d been the technician at the earlier dealership (Willingham Toyota, Pasadena, TX). and that it was me who also resolved the issue at “Main Street Toyota, Houston) only a few days later. LOLLOL
Anyway… the most common problem is the initial-conversation when the service writer (or doctor or other provider) leaps to a conclusion instead of listening to the complaint. Communication….I.E…. LISTENING…is the single most-common human failure we make.
