1. Basic Troubleshooting:
* Check the Fuse: This is the easiest first step. Consult your owner's manual to locate the fuse for the power windows. Check for a blown fuse and replace it if necessary with one of the same amperage.
* Check the Switch: Try the window switch in different positions. Sometimes, a sticky or faulty switch is the culprit. Try spraying a small amount of electronic contact cleaner (like DeoxIT) into the switch (carefully!) while operating the switch. Let it dry completely before testing. If the switch is clearly damaged, it will need replacing.
* Listen for Motor Sounds: When you operate the switch, can you hear any clicking or whirring sounds from the door? A lack of sound often indicates a blown fuse, a bad switch, or a problem with the motor itself. A grinding sound suggests something is jammed.
* Manual Override (if applicable): Some models may have a manual crank for emergency operation. Check your door panel for a small access hole that might allow for a manual crank to be inserted.
2. Investigating the Door Panel:
If the fuse and switch seem okay, you'll likely need to access the window mechanism. This involves removing the door panel:
* Remove the Door Panel: You'll need a trim panel removal tool or a flathead screwdriver (covered with tape to protect the panel). Carefully pry around the edges of the door panel to release the clips holding it in place. There are usually several screws hidden behind covers (armrest, door handle, etc.). Consult a repair manual or online guide specific to a 1994 Ford Tempo for detailed instructions – it varies slightly by trim level. Take pictures as you go to help with reassembly.
* Inspect the Window Regulator: Once the panel is off, you'll see the window regulator mechanism (the system of gears and cables that moves the window). Look for:
* Broken or Disconnected Cables: These are common points of failure. You may need to replace the entire regulator.
* Broken Gears: Similar to the cables, broken gears mean a regulator replacement.
* Obstructions: Check for anything jammed in the track that might be preventing the window from moving (e.g., debris, ice). Carefully remove any obstructions.
* Bent Tracks: If the tracks are bent, they need to be straightened or replaced. This requires some mechanical aptitude.
* Inspect the Window Motor: The motor is usually attached to the regulator. You can test the motor (with the panel removed and the wiring still connected) using a 12V power source directly (with caution and proper polarity). If the motor doesn't work, it needs replacing. Use a multimeter to verify the motor is getting power from the switch.
3. Repair or Replacement:
* Minor Repairs: If it's a simple obstruction or a bent track, you might be able to fix it yourself.
* Parts Replacement: Replacing the window regulator, motor, or cables requires some mechanical skill. You'll need to purchase replacement parts (from a parts store or online retailer, specifying your Tempo's year and trim level).
* Professional Help: If you're not comfortable working on car mechanics, it's best to take your Tempo to a qualified mechanic.
Important Notes:
* Repair Manual: A repair manual specific to your 1994 Ford Tempo will be invaluable. It will provide detailed diagrams and instructions for removing the door panel and accessing the window mechanism.
* Safety: Disconnect the battery negative terminal before working on any electrical components to prevent accidental shorts.
* Parts Compatibility: When ordering replacement parts, double-check compatibility with your specific vehicle model and year to avoid purchasing incorrect items.
By following these steps systematically, you should be able to diagnose and fix your stuck power window. Remember to take your time, be careful, and don't hesitate to seek professional help if you encounter difficulties beyond your skill level.
