zoomee99 Posted January 6, 2010 Share Posted January 6, 2010 99 RX 300 with two...maybe related... issues. Dome light does not light up when the door is opened (bulb is good) and the headlights don't turn off when in auto mode. I suspect both things are triggered by a door open/closed sensor...but I'll be danmed if I can find where it is so I can test it. Thoughts?

cduluk Posted January 8, 2010 Share Posted January 8, 2010 Yeah, the door open/close sensor is built into the door lock mechanism itself. Usually it's just a button on the door jam that compresses when the door's closed, but the Lexus engineers decided to make it more difficult for the Rx300 :( Quote Link to comment Share on other sites More sharing options...
joe913 Posted January 8, 2010 Share Posted January 8, 2010 This may be one of those "duh" questions but we need to eliminate the obvious. Is the three position switch on the dome light in the correct position so that it comes on when the door opens? Quote Link to comment Share on other sites More sharing options...

norcalmike Posted November 30, 2010 Share Posted November 30, 2010 I have this same issue on my 99. the passenger door never works and the driver door sometimes works. anyone made a howto on what to replace. if i can open up the lock mechanism and just replace the bad sensor, that would be great. thanks, mike Quote Link to comment Share on other sites More sharing options...
