Tools You'll Likely Need:
* Socket set: Various sizes, including likely 10mm, 8mm, and possibly others.
* Screwdrivers: Phillips and flathead, various sizes.
* Pliers: Needle-nose pliers can be helpful.
* Panel removal tools: To avoid scratching the interior trim.

General Steps (Consult your repair manual for specifics):
1. Disconnect the Battery: This is crucial to prevent electrical shocks and short circuits.
2. Remove Interior Door Panel: This typically involves removing screws around the armrest, door handle, and possibly the window crank (if applicable). Pry carefully with panel removal tools to avoid breaking plastic clips. There might be some push-pins involved. Refer to your repair manual for the exact location of these fasteners.
3. Access the Window Regulator: Once the door panel is off, you'll see the window regulator mechanism. The motor is usually attached to the regulator. You might need to remove some screws or bolts holding the regulator in place. Take photos as you go to help with reassembly.
4. Disconnect the Electrical Connector: Carefully unplug the electrical connector from the window motor. Make a note of how it was connected, or take a picture.
5. Remove the Window Motor: This usually involves removing some screws or bolts holding the motor to the regulator. Again, your repair manual will be crucial here.
6. Install the New Motor: Carefully install the new motor, reversing the steps you took to remove the old one. Make sure it's securely fastened.
7. Reconnect the Electrical Connector: Plug the electrical connector back into the new motor, ensuring a secure connection.
8. Reassemble the Regulator: Put the window regulator back into its place and secure it.
9. Reinstall the Door Panel: Carefully put the door panel back on, ensuring all the clips and screws are securely fastened.
10. Reconnect the Battery: Reconnect the battery and test the window.
Important Considerations:
* Window Safety: Before starting, fully lower the window. This will make it easier to access the regulator and prevent damage to the window.
* Repair Manual: A repair manual specific to your 1992 Chevrolet Beretta is *essential*. It will provide detailed instructions and diagrams showing the exact location of fasteners and how the components are connected. Generic instructions can be misleading or even dangerous.
* Wiring: If the wiring looks damaged, frayed, or corroded, you might need to repair or replace it as well.
* Troubleshooting: If the window doesn't work after replacement, double-check all connections and ensure the new motor is properly installed. There might be a fuse issue as well.
This process is considerably more involved than a simple description can convey. If you're not comfortable with automotive repair, taking it to a qualified mechanic is recommended. Attempting this repair without proper knowledge and tools could lead to damage to your vehicle.
