Door Ajar switch/sensor
 

I have a 2004 mazda rx8, and my door ajar light never goes off. And until i get it looked it, i figured id disconnect the door ajar sensors so the light would go off. Well i disconnect both sensors the one on the driver side and passenger side, and well guess what, the light did NOT go off. Any one have any suggestions?

Now i just realized, i never checked the trunk switch. How do i disconnect the trunk sensor or should i just try some wd40?

These are N/C switches so when the door is open, the switch creates a closed circuit and grounds the "door" LED (which is what you see illuminating).
That said... use a meter and test each switch to find out which one doesn't change state when you press it.

Sorry to open an old thread but it appears that....well I noticed the light only came on sitting in the seat....I don't know how or why....all I know is that after unplugging the connectors under my dear the light went off
