Procedure:
Step 1: Disconnect the Battery

Step 2: Remove the Door Panel
Use a flat-head screwdriver to pry off the plastic caps covering the screws that hold the door panel in place.
Remove the screws using a Phillips-head screwdriver.
Carefully pry off the door panel, starting from the bottom and working your way up.

Remove the bolts holding the regulator in place using a socket wrench.

Step 4: Check the Window Motor and Switch
Before replacing the window regulator, check if the window motor and switch are working properly.

Test the window by pressing the switch up and down to see if it operates smoothly and evenly.
Make any necessary adjustments to the window regulator assembly if the window does not move properly.
Step 8: Reconnect the Battery
Reconnect the negative terminal of the battery.
Test the window again to ensure it works properly.
