2005 Dodge Caravan Locks

They have their fuse in the engine compartment's power center, maybe the fuse is burnt out. Check it with a 2carpros test light, it works great, follow the directions about checking the fuses with it. If it is ok, the BCM controls the lock system and is used for diagnostics, you'll need a scanner to test the system. There are a couple of bulletins about reprogramming or replacing the BCM for this same problem. I think a fuse is bad. Ok
