1998 dodge grand caravan. The doors lock automatically when you begin to drive. They make a loud grinding noise when this happens. The locks still work but it make the sound when you lock or unlock the doors. What is the noise and how do I get rid of it?

That sound is going to be your door lock motors wearing out. I would suggest getting them replaced pretty quickly as they will soon stop locking altogether. It's not cheap, but it isn't horribly expensive either.

Hello! There is a Technical Service Bulletin (TSB) written for this problem... TSB # 23-03-99, written on 02/12/1999, addresses the Sliding Door Lock/Latch Control as the cause of the loud grinding noise you are hearing...If the vehicle was covered by warranty the mechanism would be replaced on their dime...It would appear that your vehicle is not.. Replace the Lock/Latch mechanism...
