I was turned off almost immediately when I arrived at the service bay. I was called out to the bay after I had put my materials down at a table and filled a cup with coffee. Once at the car, the service advisor, Greg, pointed out that the light switch was down when I arrived, causing the lights to be dim. I protested that I know how to move the dial to make the lights brighter, and that I had done that during the several days that the lights had caused me problems. Then he put the headlights on and showed that the lights dimmed. I assumed he was telling me not to drive with the headlights on during the day. I told him I always drive with the headlights on. My inference was that he was not listening to me. Understand that I came into the service bay with a negative attitude. I have had bad experiences will all car dealers in my 69 years. I don't come to a dealer for service unless I can't get it somewhere else. In this case, I inferred the problem with my front turn signals was caused by the replacement of the front headlights--a recall situation. I find that dealership service personnel discount whatever women say. I take offense at that treatment. That made me defensive when called out to the service bay. It didn't help that, when I returned to the waiting area, one of your employees had thrown out my coffee. When service was finished with my car, Greg told me that there was nothing wrong with my dashboard lights. That really set me off. I'd been frustrated by the problem for 4 days and I couldn't accept that there was nothing wrong with it. I became adamant that I would not leave until the problem was evident and fixed; I would not make a second trip for this problem. I suggested a serviceman drive the car. Eventually, Greg took me out to drive with, I think, Vince, a service technician. He was very nice and asked me how the car was acting up. After a short time, he put the headlights on, which caused the dash to dim. I was happy that he had been able to duplicate my problem. Then he explained the "lock" position what would prevent the dash dimming when the headlights were on. That was what I had not done in my adjustments to the light wheel; it needed to be pushed past the detent to the locked position. Vince was able to convince me that I could fix the problem myself, without triggering my defensiveness. I left happy with the service. In conclusion, the dealership will always have a threshold to overcome with me; I expect my comments to be ignored and I expect to have to fight for what I want. I'm not an easy customer to deal with. I think your service people need to treat women very carefully.
