A Step-By-Step Guide to Replace a Car’s Side Window

Follow the steps mentioned below to replace your car’s side window. 

Search For a Replacement Window

First, find a replacement window that matches the model and make of your car. Your local auto parts store or a reputed auto glass store can help you find the right replacement window. 

Removing the Broken Window

Now, remove the broken window carefully. To do this:

  • Clean up any broken glass inside the car. You can use a shop vacuum for this purpose. 
  • Now, remove any screws, clips, or bolts which hold the door trim panel in place (The car’s manual can help you find them, as they might be hidden or need other parts removed first.)
  • You might also need to remove the cranks on windows or door handles to get to the panel. 
  • Use a knife or a trimming tool to carefully pry off the plastic trim without breaking it. 
  • Once it is removed, you can take off the vapor barrier 
  • Now, clean up any glass inside the door with the vacuum.

Installing the New Window

The next step for the car’s side window replacement after removing the broken glass window is to install the new window. To do this:

  • Move the window to reach the screws.
  • Unplug the window motor.
  • Take off the rubber seal at the top of the door.
  • Unscrew and take out the old window parts.
  • If needed, fix the path on which the window moves.
  • Put the new window in carefully.
  • Screw back the parts to hold the window in place.

Reassembling it

Now, to put everything back together, follow these steps:

  • Fix the window track and put everything back. 
  • Connect the wires before fixing the door trim. 
  • Test if the window moves up and down smoothly. If it does, that’s good! If not, find adjustment screws in the door panel and fix them. 
  • Reattach the vapor barrier, door trim, and any hardware like handles or weather stripping. 
  • Gently tap the door trim into position if needed.

So this is how you can replace your car’s side window by yourself. However, if you find the process overwhelming or are not confident enough to do it yourself, it is best to seek professional help. 


In conclusion, replacing a car’s side window can be done step by step. First, find the right replacement window for your car.
