I posted this problem on the other thread but did not get any feed back, anyway here is the problem:

I noticed lately, when i turn my key to ignition on and when engine is running, and open my driver door, my door light doesn't light up and the red "door open warning light" on the dash is very dim, but the roof light does light up properly.

if I don't put the key in and open the door, the door light and dome light does light up, but no "door open warning light"...

All other doors are working properly, ie. open door, front door light, "door open warning light", and dome light does light up properly.

I did swap the door sensor on B-Piller with the passenger door one, still the same problem, so I assume the sensors are fine. I did check the fuse under the steering wheel, the "room light" fuse is good. Does anyone know what it might be? I am thinking maybe a relay under the hood. Does anyone had this problem before? please let me know the solution.

 

no one experience this??
