How to replace a car window switch

Has your window switch recently broken? Or maybe it’s glitching and becoming annoying to deal with the electrical issues associated with such a problem. Your window switch could easily be damaged from exposure to water or even wiring corrosion. It happens. So, if your window switch is on the fritz, it’s about time you replaced it. Naturally, you have two options: you could go to a mechanic and have them do a quick fix, and you’ll pay for the parts and labor, or you could just pay for the part and do it yourself in a few simple steps. 

Should you choose to take matters into your own hands when replacing your window switch, here is a quick guide to helping you get the job done. Stick with us, and you’ll have a window switch that works as well as new. 

Common signs you need to replace your window switch:

• Your window will not roll up or down
• Strange noise when you try to open or close the window
• Intermittent window operation

How long should it take to replace a window switch?

When replacing your window switch, you can expect the whole process to take around an hour to complete. 

Step 1: Check the electrical box 

Before you buy a replacement switch, always check your electrical box and fuse. A quick tip to tell if there’s definitely an issue with the fuse is if you push down on the window button and can’t hear the motor. There is a chance that it’s not the actual window switch that is malfunctioning but that you might have blown a fuse. 

When pressing down on the motor and you can hear the motor, or glass wants to move, this is a sign that there’s probably a mechanical issue and the window switch will need to be replaced.

Step 2: Buy a replacement window switch

It’s relatively easy to get your hands on replacement window switches, and thanks to online stores like MyAutoParts, you don’t even have to leave the comfort of your own home. You’ll need to check your owner’s manual for the exact part number to get your car’s specific window switch. 

Ordering your window switch online means you have the opportunity to get your specific part, and there’s no showing up to a shop where they might not even have what you need in stock. 

Step 3: Have the right tools

Thankfully, replacing your window switch is not a super complicated task, and it requires only two pieces of equipment, which most households will have. For this task, you’ll need: 

• A flathead screwdriver (a minus)
• Your replacement part

Step 4: Remove the panel 

With your screwdriver, carefully pull out the switch panel (bezel) where the window switch is located. It’s important not to force it open as there are plastic tabs that keep it in place, and you do not want to break them off in the process. Once you’ve pried it loose, use your hands to gently wiggle it out.

Step 5: Disconnect the wiring

When the panel is safely out, it’s time to disconnect it from the power source located underneath it. This is incredibly easy with newer model cars, as you’ll just need to remove the plug from the window switch. 

For an older model car, you may need to remember the sequence in which the wires are connected so you can connect it to the new window switch properly. At this point, it’s best to have someone take a picture or video or make a note of the placement, so you have something to refer back to. 

Step 6: Reassemble the power window switch

Next, you’ll take your replacement window switch and plug it in. Once it’s secure, you will carefully slide the assembly into the door mounting (its seating in the door) while ensuring that all the individual clips remain in place. Even with the power being off, check to see that the rockers move correctly. 

Step 7: Check 

Finally, turn on your car’s electrics to see if the new window switch is functioning properly. Should it still have an issue as you press the button, then the problem could be due to a faulty switch or a deeper issue with the system.

Final thoughts

Replacing your car’s window switch is one of the more simple tasks. So, for those who are confident or want to learn to take care of their car’s basic maintenance, this is a task that you can attempt to do by yourself. However, should you feel out of your depth, there’s no shame in sending it to your mechanic. Do yourself a favor though, and order your replacement window switch online to save time, cut costs, and get the best deal.
