1. Check the Fuse:
* Locate your owner's manual to find the fuse box diagram and identify the fuse for the power windows.
* Check the fuse with a test light or by visually inspecting it for a blown filament (a broken wire inside the fuse). Replace it if necessary with a fuse of the same amperage.
2. Test the Window Switch:
* Try the other window switches: Do the other windows work? If they don't, the problem likely lies with the power source (fuse, battery, etc.), not the driver's side switch.
* Try the driver's side switch for other windows: Does the driver's side switch operate the other windows correctly? If not, the switch itself is likely faulty. If it does operate other windows, the issue is most likely with the driver's side window motor or regulator.
3. Check the Window Motor and Regulator:
This requires some disassembly:
* Access the door panel: You'll need to remove the interior door panel. There are plenty of online videos showing how to do this for a 2000 Ford Explorer. Search YouTube for "2000 Ford Explorer driver side door panel removal". Be careful not to break any clips.
* Inspect the window motor and regulator: Once the panel is off, you can visually inspect the motor and regulator for any obvious damage, broken wires, or obstructions.
* Test the motor: With a multimeter (if you have one) you can test the motor for continuity. This requires some electrical knowledge. Otherwise, you can try applying power directly to the motor (with extreme caution and only if you are comfortable working with electricity) to see if it runs.
* Inspect the regulator: The regulator is the mechanism that moves the window. It's common for the plastic components to wear or break over time.
4. Check the Wiring:
* While the door panel is off, carefully examine the wiring harness for any broken, frayed, or disconnected wires. Pay close attention to the connections to the motor and switch.
Possible Solutions Based on Diagnosis:
* Blown Fuse: Replace the fuse.
* Faulty Switch: Replace the driver's side window switch.
* Faulty Motor: Replace the window motor.
* Faulty Regulator: Replace the window regulator.
* Wiring Issue: Repair or replace the damaged wiring.
Important Considerations:
* Safety: Disconnect the battery negative terminal before working with any electrical components.
* Parts: Parts can be purchased from auto parts stores, online retailers, or salvage yards.
* Professional Help: If you're uncomfortable working on your car's electrical system or mechanics, take it to a qualified mechanic. Improper repair could lead to further damage or injury.
This process is a general guide. The specifics might vary slightly depending on the exact model of your 2000 Ford Explorer. Always consult your owner's manual and use online resources (like repair manuals and YouTube videos) for detailed instructions and visual aids.
