I had to take my '05 GX in for power steering pump failure. I had the Fresno, CA Lexus dealership repair the dimming portion of my mirrors since they had to have the vehicle for a week in order to repair the p/s pump. When I picked the vehichle up, the service dept tried to tell me I didn't have the dimming feature on my mirrors until I showed them the sticker that came with my vehicle when I purchased it a couple months prior. It blew my mind, that the service dept, thought I was a stupid and ignorant lexus owner and as if I would have no idea what my car was equipped with. This idiot I talked to apparently had no idea another service rep called me the night before stating they got the dimmers to work bypassing the relays and that it should be fixed by the next day. :chairshot: So needless to say, it had to stay there longer so they could fix the dimming.
