My truck is starting to develop a mind of it's own. It doesn't want to agree with me that my passenger door is closed. Anyone know where the location of the door ajar switch is?

Thanks in advance for your help!

 

reg cab; in behind the latching assemblie on the end of the door...just soak it good with WD40

 

I agree.. Soak it with WD 40 about once a month..
These things are a nightmare to replace on the F150..
Not so bad on the Ranger, but anyhow.. they are under the lock. Just a twist and it will pop out.. but it ain't no fun job to do!!

Good Luck!!

WD40 will take care of it. Did it to mine about 2 months ago, and no problems since.

 

It seems like WD-40 worked! Thanks for everyone's help!

 

my 99 f150 had the same problem,lights and buzzer and i also sprayed wd-40 in the black plastic lever and no more lights or buzzer it works....rob
