Weirdest damn thing i ever seen. Its been a bit cold lately here in Ohio, and on sunday i went to visit some family and when i got in the truck to leave i closed the door and it didnt latch. So i kept trying and it wouldnt do it. I checked the latch itself and it moved as it should, but when i tried to close the door it wouldnt lock shut. The truck would beep at me as if i just opened the door when it bounced back so i know it was going far enough, but once the truck warmed up from the heater it latched just fine. I even made several stops between there and home with no issue, and i'll be damned if it didnt do it again when i left for work today and again when i left work to come home. Anyone expierence this before? Any ideas how to fix it?

 

Clean it and Lube it up

 

^x2 If it is working when you test it I'd bet this will fix it.
