1. Preparation:
* Gather Tools: You'll need a variety of tools, including:
* Screwdrivers (Phillips and possibly flathead)
* Panel removal tools (plastic pry tools are ideal to avoid scratching)
* Socket set (various sizes, likely including 10mm, possibly 8mm)
* Pliers (needle-nose are helpful)
* Possibly a ratchet and extensions
* Electrical tape (or shrink wrap)
* New window regulator motor (make sure you get the correct one for your year and model Contour)
* Consult a Repair Manual: A Chilton's or Haynes repair manual specific to your 1999 Ford Contour will be invaluable. It will provide detailed diagrams and steps, often showing the exact locations of fasteners and connectors.
* Disconnect the Battery: This is crucial to prevent short circuits and accidental activation of the window system. Disconnect the negative (-) terminal first.
2. Accessing the Window Regulator:
* Interior Door Panel Removal: Carefully remove the interior door panel. This usually involves removing screws around the armrest, door handle, and possibly under the door pull. Use panel removal tools to gently pry the panel away from the door, being cautious not to break any clips. Take pictures as you go to help with reassembly.
* Window Removal (Possibly): Depending on the design, you may need to lower the window completely before you can access the regulator mechanism. If so, carefully disconnect the window motor connector before attempting to manually lower the window (if it doesn't lower freely, consult a repair manual for the proper procedure).
* Regulator Access: Once the door panel is removed, you should see the window regulator mechanism. This often involves more screws or fasteners that need to be removed to gain access to the motor itself.
3. Replacing the Motor:
* Disconnect the Old Motor: Disconnect the electrical connector from the old motor.
* Remove the Old Motor: Carefully remove the old motor from the regulator. This may involve removing some clips or screws securing it in place.
* Install the New Motor: Install the new motor, ensuring it's securely fastened.
* Reconnect the Electrical Connector: Carefully connect the electrical connector to the new motor.
4. Reassembly:
* Reattach the Window Regulator: Reattach the window regulator to the door mechanism.
* Raise the Window (If Necessary): If you lowered the window, manually raise it to its original position. Some regulators may have a manual crank to assist with this.
* Reinstall the Door Panel: Carefully reinstall the door panel, making sure all clips and screws are properly secured.
5. Testing:
* Reconnect the Battery: Reconnect the negative (-) battery terminal.
* Test the Window: Test the window switch to ensure the new motor is functioning correctly.
Important Considerations:
* Wiring: Pay close attention to the wiring connections. Take photos before disconnecting anything to aid in reassembly. Incorrect reconnection could damage your system.
* Clips: Door panel clips are often fragile. Take your time and use the proper tools to avoid breakage.
* Manuals: Using a repair manual is highly recommended. It will provide specific instructions and diagrams for your vehicle's model.
This is a general guide. The exact steps may vary slightly depending on your specific 1999 Ford Contour model. If you are not comfortable with automotive repair, it's best to take your vehicle to a qualified mechanic. Improper repair can lead to further damage or injury.
