I want to sell my Lexus and would like to make sure that the lockers work. I have never used them and today I pushed and turned the switch. The first setting locks the rear and the light on the dash flashes and never stops flashing. I turned to the next setting and now two symbols flash and keep flashing. I don't feel anything clicking so I can't tell if they really locked or not. I was on my driveway. Pete Elsa, Tx
