05 odoge caravan power locks

Your question as stated is missing clarity.

Do you mean power lock buttons were functional but automatic lock/unlock stopped working. Then after removing and reinserting the lock fuse, none of the lock functions work?

The BCM controls activation of all the lock actuators. The power lock/unlock buttons at the doors request the BCM to power the specific door lock with the appropriate polarity to lock or unlock. Further, the BCM has inputs from the ignition switch and the transmission selector to issue the operator programmable automatic lock/unlock.

The typical single point of failure for all door locks is the drivers switch assembly, but it requires several troubleshooting steps to isolate other potential faults.

Check fuse F8 in the engine fusebox. It supplies power to the horn. I cannot find a fuse for the power locks, so it is possible that the F8 fuse also supplies power to the locks.

The problem is most likely the switch/plunger .
You will need to take off the door panel and look inside, with an electrical tester, and see what has failed.
The switch/plungers are quite cheaply made, and fail often.
God bless your efforts.

The locks don't work from any switch or just the driver's door switch ? The door locks are controlled by the BCM - body control module , that's were the clicking you hear is coming from there are no fuse's that are marked for the locks , fuse's for the BCM .

Door Lock System Components
The power door lock system consists of the following components:
• Driver door lock switch -- Uses a single signal wire for both lock and unlock switch activations
• Front passenger door lock switch -- Uses a single signal wire for both lock and unlock switch activations
• BCM -- Class 2 module which requires programming when replaced
• Reversible door lock actuators in each of the doors
• BCM PWR 15A fuse -- Located in the BCM fuse panel, supplies power for the door lock system

The BCM PWR fuse supplies battery positive voltage to the BCM for the door lock system.
The BCM supplies and monitors a reference voltage to the door lock switch through the door lock switch lock/unlock signal circuit. The door lock switch also receives a constant ground source. If a door lock switch is placed in the lock position, the reference voltage is taken directly to ground and the BCM senses 0.0 volts on the signal circuit. If a door lock switch is placed in the unlock position, the reference voltage is taken to ground through a 15k ohm resister that is internal to the door lock switches and senses approximately 2.9 volts on the signal circuit. This is how the BCM determines what portion of the door lock switch was activated.
The BCM, upon receipt of a door lock switch lock or unlock signal, will switch the appropriate door lock actuator control circuits to battery positive voltage. The opposing side of the door lock actuators are connected to ground internally within the BCM through the other door lock actuator control circuit and the doors will lock or unlock appropriately.
Vehicles without keyless entry have two internal drivers in the BCM to control the door lock actuators. All door lock and all door unlock. Vehicles equipped with keyless entry have three internal drivers in the BCM. Driver door unlock, passenger door unlock and all door lock. This is done to isolate the driver door lock actuator so it can be unlocked by itself using the keyless entry transmitter.

Look under the hood at the fuse/relay panel. Lift the top and look inside the lid,it will tell you witch fuse is controlling the door locks. remove the fuse to disable the locks. Or remove the door lock relay under the dash.Hope this will help.

A bad switch would not prevent the remote control receiver or another door lock switch from providing power to the lock unit. Other possibilities include a break in the wiring harness, most likely where it goes from the vehicle body into the door. and corrosion in the connector.

If the door locks and unlocks with the remote unit or with other lock buttons in the vehicle, most of the wiring harness is verified good; only the wiring to the switch that doesn't work is suspect. There are several tests that can be carried out to isolate the problem. One (if you have a way to identify the pins such as matching wires on the switch connector with those on the lock unit connector) is to unplug the switch and check the contacts for continuity while you operate the switch. You can (with the lock fuse removed so you don't risk damaging your meter) measure the resistance of the lock unit to ground from the switch connector - this verifies the wiring harness at the switch. If this checks out, put the fuse back in and measure voltage on the incoming power lead to the switch to verify that wire is good. Note: oxidation (tarnish) in the connector may prevent an adequate connection even though the wiring passes the previous tests. If the connector pins or sockets appear to be tarnished, clean them with a soft white pencil eraser if possible; otherwise use electrical contact cleaner. Do not use electric motor cleaner; that could damage the plastic.

On some vehicles, it is possible to disassemble the switch unit and clean the contacts, but you have to be very careful not to break the plastic hook tabs that hold it together. The springs in the switches can be tricky to work with also, so be careful when you take it apart so pieces don't fly away or fall out before you can see where they belong. If you discover a broken or cracked switch actuator or contact mount (part of the switch case), you may be able to repair it with ABS plastic pipe glue or JB-Weld or similar metal-filled epoxy. You can try using metal-filled epoxy to build up a worn actuator surface - put on a dab and file it to the correct shape when it is cured.

THERE WAS A SOFTWARE ISSUE FOR THE BODY CONTROLLER FOR 04-05 CARAVANS..A SOFTWARE UPDATE WAS AVAILABLE TO CORRECT CONDITION..PRETTY SURE DEALER IS ONLY ONE THAT CAN PERFORM UPDATE..TAKES ABOUT 1/2-1 HOUR TO COMPLETE..HAVE ALSO SEEN SWITCH PROBLEMS AND BODY CONTROLLER ITSELF WAS PROBLEM..CONTACT YOUR LOCAL DEALER..THEY CAN CHECK AND SEE IF NEEDS UPDATE..I HOPE THIS HELPS

clean and lubricate all moving arts, and replace switch

READ YOUR MANUAL. THERE IS A SEQUENCE INVOLVING REMOVING A FUSE WHICH RESETS THE ELECTRIC DOOR OPENER. IT IS DESCRIBED IN THE MANUAL. EASY TO DO ONE YOU HAVE THE BOOK IN HAND.

The problem is the BCM. The fix is a software update. Resetting the computer by removing and then replacing the 20 amp fuse marked 10D in the fuse box under the hood next to the battery is a temporary fix.
