About a month ago there was a fair amount of discussion concerning door lock actuators and and how to go about replacing them. It is easy to do. Do a search, and it might be on the Excursion page and you should get all the info you need to fix them cheap and quickly. I replaced the door ajar sensors in about 15 minutes, it sits next to the actuator for the locking mechanism. I will go back and look for the posts, if I find it I will pass it along. Aloha

Cbink, here are the procedures for replacing the actuators:
One hour (12 step) procedure that I have used to successfully replace a failed electric door lock switch mechanism. Please have replacement unit on hand prior to beginning these steps and note that the door lock units are different for left and right side doors.
Step 1. Window up completely
Step 2. Remove 2 hex screws from door panel. One located underneath the red reflector plate. One located underneath the power window plate. Set 2 screws and door reflector in a safe place.
Step 3. Unhinge door panel by lifting upward, then outward. Don't pull outward first or risk breaking some of the 9 plastic hooks that secure the door panel snugly to the door frame.
Step 4. Unplug the power window connector, set power window switch in a safe place, and fully remove the plastic door panel and set aside for safe keeping.
Step 5. Peel back half of the self adhesive plastic sheathing covering the door frame to gain access into the door frame itself. Begin peeling this covering on the side nearest the door lock latch locking mechanism located at the end (farthest out) of the door frame when the door is open. This is where the faulty door lock mechanism is located. The peeled back plastic sheathing can be looped up onto the door **** temporarily to keep it out of the way while you continue. At this point, it's best to place a bright light such as a halogen work lamp near the open door frame to light up the inside parts that you'll be working with.
Step 6. Locate horizontal door connector rod that moves back and forth (left to right) when your raise and lower door ****. Follow it to the lock mechanism located at the outer most point and lift up on the yellow plastic connector with your fingers to detach the rod just at that point. The yellow plastic connector just swivels upward and the rod end just pulls out of the yellow connector. If it happens to come loose or just falls off after you have swiveled it upward, don't worry as it can be placed back into the hole from which it was seated.
Step 7. Locate the pale green connector located just above the lock mechanism. This connector serves to connect a vertical rod to the door lock mechanism as well. Pull on the green connector tab and the tab just swivels open and releases the vertical rod from the outside door handle.
Step 8. Unscrew the three black screws that hold the door latch mechanism to the door. These screws are located on the exterior side of the door frame and require a star pattern screwdriver head. This star head can be found in most any cheap rachet sets that you buy from Costco or Sams that feature multiple screw head attachments. Place 3 screws in a safe place. You'll also want to detch (by pushing inward on) a small yellow clip located on a black cable that heads toward the assembly. This connector helps secure the black cable to the door frame that comes from the interior door latch toward the locking mechanism. If you don't detach it, the black cable won't get out of the way for the next step.
Step 9. Reach in and pull the entire lock assembly out. You will need to rotate the assembly 90 degrees around the vertical window guide as you pull out the assembly otherwise 2 electrical wire connectors will get in the way and keep you from getting the assembly out enough to slide out the faulty door lock mechanism.
Step 10. Unclip the electrical connection going to the door lock unit. Note, there is also a second wire connector just adjacent to this connector and it can be detached as well if it gets in the way of the first connector. Push out the plastic bushing that helps secure the connector wire bundle to the door lock mechansim. You will push this plastic bushing into the new unit at the bushing hole once the old unit is pulled out.
Step 11. The faulty unit actually slides out toward you once you lift a bit on the thin black tab that secures it to the door lock mechanism. Install new unit by sliding it completely into the same location. At this point, connect the wires back on and activate the door lock mechanism with your remote entry to verify movement in the new unit.
Step 12. Now you just reverse the steps you have just done, by beginning at step 10 and working backwards to step 2. When you finish step 6, again activate the remote entry lock open/close button to ensure you have everything correctly working prior to moving to step 5.
Hope this helps you...Best of Luck !
