Hello People from Club Lexus!

I Have a weird problem on my Lexus GS430 06.
I tried asking on the Lexus Forum here in Holland, en also the Lexus Dealer, but no one knows what it could be.... Its like this:
The car remains indicating that my door on the drivers side is open... especially with the dome light.
When i put my interior lighting on "door" then the light on the drivers side remains on.. when i try to lock my car, the car beeps en says that there's stil a door open... and the interior lights start flashing in the car... meaning i had a dead battery the next morning...

Lets start from entering the car, while my dome light is on the "door" position.
When i enter the car, en press the start button 1 time, the car ajar light is going on, and the car is beeping that there's a door open... when al my doors ar closed... but when this is happening, and i press "off" on my dome light, then its gone... when i put it back on "door" then it comes back...
Okay, now lets pres the start button again.. then, the car shows on the display that my drivers side door is open. When i put my dome light to "off" again, you see the door closing nice and easy... when i turn it to "door" again you see the door opening again...

Lets take it a step further...
When i push the start button again, and thereby starting the car, then on the display, everything is okay, while the dome light, on the drivers side is stil burning...
When i then open my drivers side door, you'll see it open and close nice and easy on the display. So meaning.. that its not the switch on the door right?

Okay... this is where i'm at so far....
I have switched the switches from the doors from left to right, and it still remains the same...

Also i have tried another dome unit from a Lexus GS450h... and its still the same... so thats both not it...

also i have opend my driver side door panel, en removed al the connectors, en stil the same thing....

i really do not know where to search now...
Can any of you help me with this strange interior light problem??

I'm sorry if my english is not so good... i have tried my best

check the switch on the door jam

BinaryJay

Yes, they suck. Take it out and look for rust, the bolt is the ground for the harness. The part is cheap only a few bucks, I would replace it.

Erikzalm

Thanks!

But I have already switched the door switches from left to right, and its stil the same... so it is not the switch... or else i would have the problem on the other side now right?

SILENTM

How about the switch wiring/ connector

Erikzalm

I have also disconnected the whole door, and its stil the same problem...

SILENTM

The switch is not located in the door its on the body/door jam (b-pillar)

Erikzalm

But I have already switched the door switches from left to right, and its stil the same... so it is not the switch... or else i would have the problem on the other side now right?

I'm talking about the wiring to the switch and not the switch itself now. so what ever is between the light and switch ( i.e. wiiring, connectors, control module and fuse if any). May need to see a wiring diagram

Erikzalm

Okay, I'll take a look a that... I really need a wiring diagram.. but its so hard to find.. The wierd thing is that he gives a "shift to P" when i open the door when the car is in Drive... so the switch en the wiring must be good right?? I'm gonna search for a diagram! Thanx!

SILENTM

wire could be shorted/ open

Erikzalm

Okay okay, thanx! I'll check it out when the wheather gets better
