Mazda Repair Questions? Ask Mechanics for Answers ASAP
Hello I will help you with your question,
Spray the door latch openings with WD-40. Really soak them and then slam the door 10 - 15 times. Not too hard you don't want to break it but a good solid close.
This should free the door switch in the latch and turn off the warning.
There is no fuse for this switch, the power comes from the instrument cluster. Short of replacing the door switch in the latch or cutting the wire leading to the switch you will need to repair the operation of the switch.
Try the WD-40 it usually works.
