1. Check the Obvious:
* Remote Battery: Start with the simplest solution. Replace the battery in your key fob. Weak batteries can cause intermittent or complete failure of remote functions.
* Key Fob Programming: If you have multiple key fobs, try the other one. If only one fob is affected, it might need to be reprogrammed to the car. Consult your owner's manual or a Ford dealership for instructions on reprogramming.
* Door Lock Actuators: Make sure all the door lock actuators on the driver's side are working. Try manually locking and unlocking each door. If one is jammed or broken, it could interfere with the automatic system.
2. Investigate Detailing-Related Issues:
* Water Intrusion: Detailers often use water and cleaning solutions. It's possible water got into the door lock actuators, wiring, or the central locking module. Allow the vehicle to completely dry. If possible, carefully inspect for visible water damage.
* Dislodged Connections: The detailing process might have dislodged a connector related to the central locking system. This could be under the door panels, in the door jamb, or near the central locking module itself (location varies by year). You might need to remove door panels and carefully check all connections for security. (This requires some mechanical aptitude; consult a repair manual if you're uncomfortable doing this.)
* Damaged Wiring: While less likely, it's possible a wire was pinched or damaged during the detailing process. Carefully examine the wiring harnesses in the doors and along the car's sides for any signs of damage or fraying.
3. Check the Central Locking System:
* Central Locking Module: This module is the brain of the central locking system. A faulty module could be the cause, although this is less likely given the issue started after detailing. The location of this module varies by year and model – you'll need to consult a repair manual or online forum dedicated to 1997 Ford Explorers.
* Fuses and Relays: Check the fuses and relays associated with the power door locks in your owner's manual. A blown fuse or bad relay could easily cause the issue.
4. Professional Help:
If you're not comfortable inspecting wiring or removing door panels, take your Explorer to a qualified mechanic or an auto electrician. They have the tools and expertise to diagnose the problem accurately.
Important Note: Before working on any electrical components, disconnect the negative battery terminal to prevent accidental short circuits. Always consult a repair manual for your specific vehicle year and model to avoid damage or injury.
