door ajar light problem
 

i have a 2000 ford ranger and usually everytime i start it the door ajar light comes on. ive slammed the door shut but its just tempormental. where is the switch for that year truck?

On the door jam area where the door latches. Spraying it will WD-40 also works to free it up

the switch is in the door latch. its a very common problem that can often times be remedied with WD-40. shoot some WD-40 into the latch and open and shut the door several times to work it in. it should clear up the issue. i had this issue several years ago, not knowing about the WD-40 trick at the time i replaced the door latch assembly that cost about $100 if i remember correctly only to have the door ajar light problem come back just a couple months later. i found out about the WD-40 trick and tried it and its been fine since. lol sorry, i was kinda rambling there.

edit: i just so happen to have a pic of the latch assembly. the part my thumb is on is the switch.

Just a slight addition that worked for me to get that 'door ajar' light off. I kept having it turn on when i'd take a corner, and I'd slam doors too to get it off. One day, I discovered that my passenger side ext. cab door wasn't properly shut, and wiggled quite a bit. I slammed it good n hard, and no probs since :D

mine was doing this also! the passenger door. but aaron_ariens told me to spay some WD-40 and man it worked instantly lol i was shocked on how it worked. its been over a week now and its been working great

wow i just tried this right before going to get to latches, work right away. great adivse
