I have a 99' RX300. AS with most cars of any make, when you open a door the interior lights come on until the door is closed or shortly thereafter. However, my front passenger door does not activate the interior light like the other doors of the car. Now, sounds like a petty problem until you realize that the security system locks the car after 30 seconds if no door is opened. Therefore, if I unlock the car to get something or do something through the passenger door, since this door does not activate the iterior light then the car security system relocks the car and sets off the alarm. On all cars that I have owned in the past there was a small post that the door would release when opened that turned on the lights, however I can not find anything on the door or door jam that activates the lights and disables the security system. Help, very frustrating at times.
