One dealer didn’t try to figure it out, the other dealer has looked 3 days for the problem, and when I got home with it after 3 days, the yellow wrench came right up again. I figure it must be a hard problem to figure out, but if it isn’t going to cause any problems with the car, I will just keep driving it and ignore the notice on the dash. When the mechanics don’t know what to do, they are using the computers a lot, I don’t know where to look next. I read your articles in the Blade all the time and really enjoy reading your responses, you are pretty entertaining. I hope you know where I can get help for this problem. Thanks.
