I have to add some more, I'm on the box.
This is how my day went today. I got a buick in with an Onstar problem, I tested the car the system worked but I was told by the service manager to spend an hour on it and see if I can find a problem. After an hour I found nothing. For my hour's worth of work I got paid 18 minutes. Next car I got was a Lesabre for poor fuel economy. Road test scanned the car, the customer was used his dash average fuel economy to judge mpg. I questioned the owner and found out he is not resetting his ave economy system right. For this job I got zero pay. All because the writer didn't ask the right questions and the owner didn't know how to work his car. That is 2 cars out of 8 for me today and 2 cars I lost money trying to fix all because of errors made by the owner or the writer. Don't think for one minute this is rare I get this everyday. I started the day in the hole, yet at the end of the day I have to have more than 8 hours made. I left today making 11 hours in 8 hours of time.
The most important thing I want you to remember is that the more information you give me the better and faster I can fix a car. And at least open up your owner's manual and read it your answer might be in there which will save you the time of coming to a dealer and wasting your time. I would love to sit with everyone and explain the problems with their cars, what needs to be done to keep the cars going, I want to take care of the people but I also have to make a paycheck. And coming to a dealer with a non-problem takes away from me. Education is The most important thing I ask from you. Please do the most you can to know your car and learn. I don't have a problem with being asked questions and I will do my best to answer them all.
