What you'll likely need:
* New window regulator: This is the most important part. You can find these online (Amazon, eBay) or at an auto parts store. Make sure you get the correct one for your specific door (driver's side or passenger's side).
* Screwdrivers: A variety of Phillips and flathead screwdrivers, possibly including a security bit if your car has them.
* Panel removal tools: These plastic tools help pry off interior door panels without scratching them. You can find these at auto parts stores.
* Pliers: Needle-nose pliers might be helpful for reaching small screws or clips.
* Socket set (possibly): Depending on the design, some screws might require a socket.
* Patience: This is a fiddly job.
General Steps (This is a simplified overview. Refer to a video for detailed instructions.):
1. Remove the interior door panel: This usually involves removing screws around the door handle, armrest, and sometimes the door speaker. Be careful; some clips are fragile. The panel is usually held in place by clips, so gently pry it away using your panel removal tools.
2. Locate the window regulator: Once the panel is removed, you'll see the window regulator mechanism. It's connected to the window and the motor that moves it.
3. Disconnect the window motor: You'll likely need to disconnect the electrical connector to the motor.
4. Disconnect the window: Carefully disconnect the window from the regulator. There are usually clips or some type of attachment mechanism holding the window to the regulator.
5. Remove the old regulator: This often involves removing several screws or bolts holding the regulator to the door.
6. Install the new regulator: Carefully install the new regulator in the reverse order of removal. Make sure everything is properly aligned.
7. Reconnect the window: Carefully attach the window to the new regulator.
8. Reconnect the window motor: Reconnect the electrical connector to the motor.
9. Reinstall the door panel: Reinstall the interior door panel, ensuring all clips and screws are securely fastened.
10. Test the window: Test the window to make sure it goes up and down smoothly.
Important Considerations:
* Safety First: Disconnect the car battery's negative terminal before starting any work to avoid electrical shocks.
* Window Weight: The window is heavy; support it carefully while working to avoid damage.
* Clips and Fasteners: Take pictures or make notes as you remove parts to ensure you put everything back correctly. Some clips might break, so be prepared to replace them.
Again, watching a YouTube video specific to your car model is crucial. This detailed description can't replace the visual guidance of a video demonstrating the exact process for your 1999 Pontiac Grand Am. If you're not comfortable with this level of car repair, take it to a qualified mechanic.
