1. Preparation:
* Safety First: Disconnect the negative battery terminal to prevent electrical shorts.
* Gather Tools: You'll need a variety of tools, possibly including:
* Screwdrivers (Phillips and flathead, various sizes)
* Panel removal tools (plastic pry tools to avoid scratching)
* Socket wrench and sockets (likely metric)
* Pliers
* Wire cutters/strippers (if splicing wires)
* Electrical tape
* New power window motor (ensure it's the correct one for your Cougar's year and door)
* Possibly a torque wrench (for proper tightening of bolts)
* Repair Manual: This is crucial. It shows you exactly how your car's door panel and window regulator assembly are put together.
2. Door Panel Removal:
* Carefully remove the door panel: Start by removing the obvious screws around the edges of the door panel. There are usually screws hidden under door handles, armrests, and speaker grilles. Use panel removal tools to carefully pry the panel away from the door. The panel is usually clipped into place, so work slowly and gently to avoid breaking any clips. Take pictures as you go to help with reassembly.
3. Window Regulator Access:
* Once the panel is off, you'll see the window regulator mechanism. This is the assembly that moves the window up and down. The motor is usually part of this assembly.
4. Motor Removal:
* Disconnect the electrical connector: Carefully unplug the electrical connector from the window motor.
* Remove the motor: This is where the repair manual is essential. The method for removing the motor varies depending on the design of the regulator. It might involve removing bolts, clips, or other fasteners.
5. Motor Installation:
* Install the new motor: Carefully install the new motor, reversing the removal process. Ensure it's correctly seated and all fasteners are tightened properly.
6. Reassembly:
* Reconnect the electrical connector.
* Reinstall the window regulator.
* Reattach the door panel.
7. Testing:
* Reconnect the negative battery terminal.
* Test the window: Operate the window switch to ensure the new motor is working correctly.
Important Considerations:
* Window Regulator Condition: While replacing the motor, inspect the window regulator itself for wear and tear. If the regulator is damaged or broken, you'll need to replace that as well. A faulty regulator can cause new motors to fail prematurely.
* Wiring: Inspect the wiring harness for any damage or breaks. Repair any damaged wires before reinstalling the motor.
* Lubrication: Lubricate the window regulator mechanism with a suitable lubricant to ensure smooth operation.
* Professional Help: If you're uncomfortable with any part of this process, it's best to seek professional help from a qualified mechanic. Incorrect installation can lead to damage to your vehicle or personal injury.
Remember, this is a general overview. Consult a repair manual specific to your 1997 Mercury Cougar for detailed, illustrated instructions. Improper repair can lead to injury or further damage.
