I purchased a 2005 Mazda Tribute two months ago and needless to say I can not stand to drive it often because of the door ajar dinging sound that goes on and off no matter what it doesn't matter if it's in park or I'm driving down the road I had to take out all the interior light because it killed one battery and had to purchase another one. I have tried to WD-40 spray inside the door latches everyone even back . This is driving me crazy! If anybody can tell me how to fix this I would be internally grateful

 

try getting a used one , or maybe a loose wire
