Power door lock problem

If the actuator works the problem could be the power supply to it. A common fault is the wiring loom. With the tailgate wide open lookup between the tailgate and body where the hinges are. Off to one side there will be a dark coloured rubber or plastic tube across the gap. This is the wiring to the lights and features in the tailgate. Over time this can get worn and the wires can wear and snap. A good auto electrician can fix this for you.

My tailgate won't lock on my 2009 Grand Caravan. The striker its stuck on unlock?

known faults is crankshaft sensor or immobiliser
lock all doors by hand unlock by key fob and then physically check that everything unlocked as immobiliser will give trouble if there is a door or tailgate that doesn't lock /unlock
hope this helps

The fuse box for the sliding back doors and the tailgate are in the 'secondary fuse box' under the hood:

#2 40 amp fuse - Left Power Sliding Door
#3 40 amp fuse - Right Power Sliding Door
#4 40 amp fuse - Power Tailgate

Don't know if you were referring to the doors or tail gate but if you were talking about the doors and trying to use the button to open them, make sure the MAIN switch is in the ON position or you will have to open manually. Any info, including fuse locations, are located in your owner's manual

Hope I was able to help you, please rate my post if this works out for you.

a weak door lock actuator that locks the rear tailgate

The locks are applied by a door lock actuator in each door & tailgate. See which one it appears to be. Once located disassemble door or tailgate & see if something is interfering with its operation. If nothing hitting or rubbing on it. The actuator may be lubed with penetrating oil. If that cures the noise your done. If not you will need to replace actuator.

it sounds as if there is a wire or the door lock actuator is bad on the back door as well as the tailgate give these websites a try www.alldatadiy.com and www.autozone.com if all fails stop by your local Jeep dealership in the parts department and they be able to print you off the pictures and diagrams you will need wish you the best of luck Michigan Man.

check the remote and repair .

Try to reset the tailgate by removing the no.7 (7.5 amp) fuse in the underdash fuse box. Open and close the tailgate manually, reinstall the fuse, and try the open tailgate button. If that doesn't work you would have take it to the dealer, where they can check for DTC's (diagnostic trouble codes). Honda Al

Unfortunately, This is a very common problem with Ford Explorers! Ford replaces the locks when it encounters this issue. I managed to unseize my passanger door and tailgate lock, but the drivers door lock is broken beyond repair. You can purchase new remotes for your explorer and program them very easily. Just google ford key fobs...
