Spray some wd40 in the latches and open and close the doors a few times!

 

^^^ This.

Had that problem about 8 months ago. Was a pain... My interior light wouldn't go off and it said the door was still open.
Sprayed some WD40 and not a single problem since.

 

Thanks guys I'll give it a shot

 

I put lithium grease in there cuz wd40 is a solvent. Been like a year and a half
