How to change the master window switch on GMC Sonoma 2001-2004

Do it yourself, change the master window switch on your GMC Sonoma, the model produced between the years 2001 and 2004. You will require a flat blade screwdriver and a new window switch module to make this replacement. The process is very simple and it will take you less than 15 minutes.

     In the beginning, after you open the front door, on the driver’s side, you can start by prying out the window switch from the door panel. You can do it by hand, by lifting up on the switch from the right side, to the interior of the car, as you can see in the next picture. If you find it easier, you can use a flat blade screwdriver or some other tool.

     After you release the switch you will have to get beneath it and disconnect the four plugs that power the buttons (see image below). They have different securing tabs but you can remove them by hand, helped by a screwdriver.

     After you unplug the harnesses, you can replace the entire switch (plastic bezel and modules) or the modules with buttons, separately. This can be done quite easily, using the same screwdriver, by simply prying them out (they are not held by any screw). After you make the replacements, install back the connectors and insert the switch into the door panel with the left side first (the one to the exterior of the door). These are the simple steps you need to follow, if you wish to remove and replace the master window switch on your GMC Sonoma, the model made between the years 2001 and 2004.
