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.

Same problem
 

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

Door sensor screw
 

what size screw or bolt attaches the passenger door sensor on a Mazda RX eight? Mine is missing.
I can’t find the sensor for the driver side.

I have a similar issue. My light never goes off and it faults out the security system when I try to lock it. Then the car becomes useless till I disconnect the batter for like 30 minutes. I click both side and hear them actuate something so they seem to work. The light dims when doors are shut but never goes off. Are there other door adjar sensor besides the obvious 2? Why doesn't the car recognize it immediately after ecu reset? My truck is broken are there sensors there?
