DIY, change the master window switch on your Toyota Corolla, made between the years 1993 and 1996. This is a simple replacement that can be done in less than 10 minutes, using only a flat blade screwdriver and a Phillips screwdriver.
In order to access the main window switch, the one that controls all the windows and the lock doors button, you have to open the driver’s door. There, using the tip of a flat blade screwdriver, pry out the switch, as you can see in the image below. You may consider using a rag wrapped around the tip of the screwdriver, if you wish to be extra careful with the plastics on the door.
After you release the switch, you have to unplug the electrical harness that powers it. It is located underneath, as seen below and can be disconnected by hand. If you find it difficult, you can use the flat blade screwdriver.
Now you can replace the switch with a new one. If you need to separate the plastic bezel from the module of the switch, you can do it by removing the three Phillips screws around it. If not, you can just plug back the electrical harness and insert the new switch into the door panel. This is all you have to do, if you need to remove and replace the master window switch on your Toyota Corolla, the model produced between 1993 and 1996.
